Precision engineeringand nanotechnology
converge
WITTENSTEIN, already an innovation leader in the fieldof mechatronic drive technology, has recently expanded
its expertise with a further competency – nanoprecise
measurement systems for high performance engineering– together with Munich-based attocube systems AG.
attocube, which for several years now has been a wholly
owned subsidiary of the WITTENSTEIN Group, will takeadvantage of the upcoming Hannover Messe 2017 tounveil the industrial grade IDS3010 sensor with subnanometer resolution. Dr. Dirk Haft (Management Board,
WITTENSTEIN SE) and Dr. Martin Zech (Management
Board, attocube systems AG) explained the backgroundto this innovative development and the technical USPs in
an interview with move.

move: Dr. Haft, WITTENSTEIN is a manufacturer of precision drive systems for industry.
attocube delivers equipment for world wide
research institutes such as nano-accurate
positioning drives, cryostats, microscope systems and interferometry. How does all of that
fit together?
The bridge between the two companies is our
striving for absolute precision. We both produce drives that have to satisfy the most demanding requirements. We differ in terms ofthe number of decimal places: WITTENSTEIN
develops and manufactures micrometer-precise components whereas attocube is at homein the nanometer range. These two worlds are
currently converging more and more. Sub-micrometer manufacturing precision is increasingly in demand in a growing number of industries and products. On the sensor side, aneasy-to-integrate, ultra-precise measurement
system represents an important building blockhere. Even today, I still find it very remarkable

4 movethat Dr. Manfred Wittenstein (in the meantime
Chairman of the WITTENSTEIN SE Supervisory Board) recognized the need for more precision in mechanical engineering as long ago as
2007 and against this background initiated thecooperation with attocube.
Dr. Zech, what does the name IDS3010 standfor and what exactly does this tiny device do?
IDS stands for ‘Industrial Displacement Sensor’: it’s a contactless interferometric sensor
that can measure positions, speeds and acceleration or vibration with extreme precision.
The German National Metrology Institute (PTB)
has confirmed a measurement uncertainty of
0.0 ppm up to 3 m. This means that our instrument is capable of measuring with practically no deviation from the standard meter. It’s ameasurement system that theoretically works
with infinite accuracy! We measure positions
with a resolution of 1 picometer (10 -12 m) at afrequency of 10 MHz, so that the measurement

signal contains absolutely all relevant information on the movement. That’s why we prefer totalk about this product as a ‚motion sensor‘.
In the engineering industry, on the other hand,people are accustomed to having a separate
sensor for every measured variable, for instance a glass scale for the position and an acceleration sensor for vibration. To us physicists,
this is all just motion, in other words one measured variable that we determine very precisely
and evaluate accordingly.
Dr. Haft, in what application areas does a demand for such a high precision exist today?
We don’t need to look far. Very accurate
pitches and low tolerances are essential for
WITTENSTEIN’s compact Galaxie® Drive System. Increasing the accuracy of the pitch is
generally a good way to achieve a better distribution of the internal forces acting on theteeth of a precision gearhead. More precise
tooth geometries mean lower peak stresses

Interview

Dr. Dirk Haft (left) is responsible forinnovation on the WITTENSTEIN SE
Management Board. On account of his
previous position on the Management
Board of attocube systems AG, healso bridges the gap between the
WITTENSTEIN engineering world andthe attocube nano world.
Dr. Martin Zech (right) took over asManaging Director of attocube systems AG after seven years as head of
product management and R&D. Together with quantum physicist Professor
Khaled Karraï and Dr. Dirk Haft, he wasclosely involved in the development of
the novel interferometric measurement principle to market maturity.

and higher maximum loads. In multi-row roller
bearings, too, there is a fundamental correlation between the distribution of internal forces
and the smallest possible manufacturing tolerances because these systems are hyperstatic.
Precision manufacturing, and hence also theability to measure with sub-nanometer resolution, is vitally important to enable existingmechanical systems to be developed witheven more power density. Furthermore, current technological advances are quite clearly
focused on miniaturization and, linked to this,increased product precision. It’s now up to theengineering industry to follow suit with its production machinery.
Dr. Zech, could you cite an example of a
scenario where the benefits provided by the
IDS3010 have made a critical difference to asystem’s use?
Yes, of course. A manufacturer of hard drives
wanted to determine the production-related

runout of the motor shafts at operating speed –which, don’t forget, is 5400 or 7000 rpm.
There was no measurement system in the market that offered the bandwidth and accuracy
necessary to do this. It was a simple matter forus, though. The IDS3010 is an optical instrument which allows us to measure the movement of the shaft directly and tell the customer
the exact angular position at which the greatest runout occurs. Our sensor is contactlessand no forces are exerted. The laser finds its
way into even the most confined spaces and isvery easy to integrate into production systems.
It’s an unbeatable combination!
Dr. Zech, what applications is the IDS3010
best suited for?
As we see it, interferometry – and specificallythe IDS3010 – is the outcome of a cross-sectional technology. As a pure displacement
sensing system, the IDS3010 is an attractive
alternative for all high precision applications in

production machinery, measuring machines,
in-process quality inspections, the semiconductor industry or productronics – in otherwords, in any sector under strong pressure todeliver maximum precision. If the IDS3010 isused as a vibrometer, new opportunities are
simultaneously created for measuring vibration– for example, due to imbalances – contactlessly, extremely precisely, easily and fast. The potential is huge.
Dr. Haft, how can you persuade the engineering industry of the advantages of the new technology?
In our experience potential customers are
keen to learn more about the new technology upfront and test it at their leisure. We offera loan service for this reason. More than 70%
of all loans result in production use. That’s anexceedingly high success rate.

Limitations of present-day sensor technologies
Glass scales are currently considered to be the benchmark in industry. When it comes to submicron measurements, however, the manufacturing process means
these scales quickly come up against their limits. Their
precision cannot be significantly increased. There is also
another limiting factor which impacts on the accuracyof today’s displacement sensing systems: since they areattached to the machine bed, they are always positioned
parallel to the workpiece a certain distance from it. As aresult of this, the measured position merely corresponds
to the position of the moving sensor head and not to theexact position of the target (workpiece or tool). Systematic errors, like Abbe errors due to guides and bearings,
accumulate between the sensor and the workpiece. Variable operational errors such as differences in thermal
expansion, deformation of the machine due to process
forces, wear or vibration, etc. additionally have to be taken into account. These deviations cannot be determinedby ordinary displacement sensing systems with measuring points which are too remote from the ‚action‘.

The IDS3010 can be operated with different sensor heads: ultracompact heads for the most confined spaces or alternative designs
where priority is given to easy alignment or to compatibility with avariety of target materials (glass, aluminum, ceramic, etc.).

8 move

The attocube solution: measurements directly at theworkpiece or tool
The solution to these physical and practical limitations entails a departure from established measurement principles in favor of direct
measurements of the workpiece position. attocube’s IDS3010 sensor is based on a novel interferometer technology which uses laser
to “target” workpieces, shafts and tools or machine slides opticallyand contact-free. The above-mentioned measurement errors are effectively prevented in this way.
The multi-channel displacement sensor is comprised of two subsystems: the basic unit and the sensor heads, which can be supplied indifferent versions for a maximum working distance of up to 5000 mm.
Up to three sensor heads can be connected to the compact basic
unit (19.5 x 5 x 5 cm), enabling simultaneous measurements in up to
three axes. These tiny heads contain only passive optical components and are connected to the basic unit via optical fibers.
The 0.0 ppm measurement uncertainty which is achieved between 0
and 3000 mm has been officially confirmed by the German National
Metrology Institute (PTB). The sensor can thus be said to work withtheoretically infinite accuracy. There is no longer any need to calibrate machines and axes if the sensor is integrated there.
The fiber based design, the very small sensor heads and thefact that the basic unit can be installed in any position mean that

directly on rough targets with very low reflectivity such as silicon wafers, glass or ceramic.
Measurements on plastic, aluminum, copper or polished steel surfaces are also not a problem. If the surface is not sufficiently reflective, plane mirrors with a diameter of 5 or 9 mm – or the so-called
retroreflectors in attocube’s range of accessories – can be used.

Fiber based sensor heads: added ﬂexibility

surfaces, the sensor developed by attocube is also capable of focusing measurements by forming the laser beam and can even measure

The IDS3010 was specially developed for the industrial market. It
ships with a web server, making the sensor compatible with Industry 4.0 applications: data communications, alignment, initializationand configuration can be controlled, adapted and monitored remotely from any location. An integrated, visible pilot laser simplifies
the alignment and setup process. The actual signal strength is indicated by a simple bar. After mechanical alignment, the IDS3010
is initialized and instantly displays the distance between the sensor
head and the target.
The attocube interferometer – a disruptive,
cross-sectional technology for the engineering industry
The ultra-compact dimensions of the basic unit, the tiny sensor heads and the precision of the IDS3010 are so extraordinary that developers and engineers are now compelled to reassess and rethink existing solutions in precision engineering.

How it works:
the IDS3010 optical displacement
sensing system

Infrared light is produced in the basic unit of theIndustrial Displacement Sensor (IDS) and guided into
the sensor head via a glass fiber. Inside the sensor
head, part of this light is reflected back into the device
through the fibers. The remainder exits from the glass
fibers, is reflected by the target – for example themachine component or an applied mirror – and coupledback via the fibers to the basic unit. The two beams
which are reflected on the sensor head and the target
interfere with each other. The distance between thesensor head and the target can be determined from thetotal intensity of the interfered light.

paths to one goal

Gearheads made by WITTENSTEIN alpha stand forthe highest levels of technical excellence. They demonstrate this in countless applications. If you look overthe shoulder of the designers and product managers
responsible for electric drives, you’ll notice that gearheads and drive trains are often designed and sizedbased on different sets of requirements and criteria.
“You often only need a small amount of information to design a gearhead”, explains Timo Markert, Product Manager at WITTENSTEIN
alpha. “Other, more complex design tasks, for example involving
shaft and bearing calculations or electrically preloaded drives, require more detailed calculations of the kinematics or the load requirements.” Whereas some people want to arrive at the optimum
gearhead in a matter of seconds, others insist on a drive design thathas been well thought-out from A to Z. “Each user group can choose
the software solution that best meets their needs from our portfolioof sizing tools”, Timo Markert adds.
The SIZING ASSISTANT and cymex 5 cater for totally different
drive design requirements and procedures – which is why we provide two separate tools. It is therefore only logical that WITTENSTEIN
alpha should continuously maintain and expand both the portfolio
itself and the individual tools: the next release of cymex® 5, for example, is due out this summer. In addition to the existing databases
for racks and pinions, it will also include WITTENSTEIN alpha’s new‘preferred linear systems’ in all performance classes.

Torque multiplier 4.0
WITTENSTEIN designs a heavy-duty
engine with smart electronics

The harshest possible surroundings and the most severe
stresses imaginable – like here on a wind turbine where bolts
with M160 threads or larger typically have to be tightened toas much as 200 kNm – are the norm in the characteristic
operating environments for alkitronic’s heavy-duty torquemultipliers.

Wherever bridges are built, wind turbines
erected, aircraft maintained, industrial facilities
constructed or heavy machinery and heavyduty engines installed, heavy-duty torquemultipliers from the Ingolstadt firm of alkitronic
are a familiar sight. A new torque multiplier has
just been added to the portfolio –it is equipped with a sensorless sleeve valve
engine as well as smart electronics with
Industry 4.0 connectivity from WITTENSTEIN
cyber motor.

16 movealkitronic has been developing and producing pneumatic, hydraulicand electric screwing tools for professional use in various industrial
fields ever since the early eighties.
“They’re used to bolt threads with up to 200 kNm of torque”, explains Alexander Kipfelsberger, Managing Director of alkitronic. Yet
bolting alone will no longer be sufficient in the future. “Users are
longing to realize even more complex bolting processes with new
operating modes; they come to us wanting to know how monitoring and documentation of these processes can be streamlined, forexample”, he replies when asked where the market’s priorities lie.
The idea for the smart torque multiplier was born. “It was obviousthat we’d have to tread completely new paths as regards the engine technology and the electronics”, Alexander Kipfelsberger recalls.
The question was ‘Who with?’.
“WITTENSTEIN cyber motor GmbH convinced us with their businessmodel – customized motor and electronics development that also
permits an efficient transfer to series production”, he continues. Following a successful feasibility study, an ultra-compact drive module
came into being at WITTENSTEIN in a bespoke development process.

Applications

Inside view: The electronics of alkitronic’s new electric torque multipliers are
based on a modular platform from WITTENSTEIN cyber motor, which enables
customer and application-specific requirements – both technical and commercial – to be satisfied very efficiently.

Compact drive system: motor and electronics in MINI design
Miniaturization, Innovation, Networking and Intelligence – WITTENSTEIN’s MINI strategy is clearly reflected in the requirements for the
new drive system. This consists firstly of a sensorless synchronous
motor in a cylindrical frame which is easy to integrate and service – adesign that permits simple and uncomplicated mounting above theoperating handle. The completely redesigned drive system electronics are likewise packed into the limited space available in the torquemultiplier housing. “They’re based on our modular electronics platform, which enables customer and application-specific requirements– both technical and commercial – to be satisfied very efficiently”, explains Patrick Rommel, a sales engineer at WITTENSTEIN cyber motor. “Thanks to the innovative processor technology, the new torquemultipliers are now digitally controlled for the first time. As a resultof this, alkitronic has been able to integrate up to seven operating
modes plus a series of protection and monitoring functions”, he adds.
The significantly improved control characteristics also pave the way
for much higher repeatability. “That’s a crucial argument, especially in applications where several torque multipliers have to be operated simultaneously and exactly in sync”, Alexander Kipfelsberger
emphasizes.

Future-proof system on board
The electronics for the new torque multiplier have a memory unit,
which acts as a data logger for recording and storing the bolting
torques. There is also a wireless Bluetooth module on board. The
multiplier load data which is measured for each bolting process canbe read out directly on the construction site using a smartphone ortablet, for example, and then documented transparently later on ata central location.
The fully integrated graphical user interface with display and keyboard control is likewise new; together with the Bluetooth functionality, it opens up an array of customizing options – for instance tomake servicing and maintenance far smarter than ever before. “In
the future, our traders around the world will normally be able to repair,
replace and program defective bolting systems out there in the fieldcourtesy of the plug & play design”, says Alexander Kipfelsberger.
“Torque multiplier 4.0” becomes a reality
Data logging and wireless transmission do not simply enable intelligent and flexible applications; they also fit the torque multipliers for
Industry 4.0.

WITTENSTEIN in all axes: view of the WITTENSTEIN alpha drives for thetwo servo mechanisms which flip over the wooden panels near thecover layer feeding station

Lisocore® – the new, patented lightweight material based on natural
fibers from Lightweight Solutions GmbH – is up to 70 percent lighter
than conventional composite wood panels. The company has trod
new ground with it in many respects in the market for lightweightsystems and succeeded in arousing the interest of numerous potential customers: its special properties create exciting opportunities
in furniture production and interiors, exhibition and display systems,
interior fittings for motorhomes, ships and yachts, stage and set construction, transport packaging and logistics.
The right partner to implement the engineering
The main challenge was to manufacture the lightweight panels ina technically and commercially efficient way – a project which was
actively supported by the German Ministry of the Environment withfunding from its Environmental Innovation Program. Unfortunately
though, boards aren’t made with money alone. “We soon realized

18 movethat no suitable machines or standards for our special manufacturing requirements existed in the market, nor was there any extensive
experience we could draw on”, remembers Michael Schäpers, Managing Director of Lightweight Solutions and inventor of Lisocore®.
The Bavarian firm therefore decided to design the necessary production line with automated handling system itself. “It wasn’t an easy
undertaking because many of the requirements, like the servo drive
technology for handling the panels, only became clear gradually andthey’ve also changed a number of times since.”
Luckily, lws maschinenbau GmbH – a subsidiary of Lightweight
Solutions – was able to put its trust in a competent partner. Michael
Schäpers was thoroughly impressed by the consulting expertise heencountered while going over the drive design with WITTENSTEIN’s
engineers: “The fact that WITTENSTEIN alpha provided us with

broad and prompt support throughout the project life in the form oflarge-scale simulations and detailed sizing calculations was crucial
to our ability to control the handling kinematics safely and reliably”.
Cleverly calculated kinematics – WITTENSTEIN in all axes
The Lisocore® production line has a footprint measuring around 500
square meters and a capacity for two million square meters of thelightweight material per year. “The line drills cover layers made fromdifferent materials, either with or without a decorative coating, applies
the adhesive fully automatically and then combines these layers withthe 3D core”, explains Marcus Wehner, Manager Sales / Research& Development at Lightweight Solutions. All kinematics relevant for
performance were simulated and optimized by WITTENSTEIN during
the project phase with the help of the cymex® 5 sizing software. “Thisproved to be a particular challenge when it came to the pivoting unitof the servo mechanism for flipping over the cover panels because
rotary and linear motions are superimposed there simultaneously”,
adds application engineer Daniel Meißner of WITTENSTEIN alphaGmbH’s Sales Office South-East.

systems. “The line has about 100 axes altogether, each of which isequipped with one of our servo gearheads”, comments Sven Sanitz,
the Regional Sales Manager responsible.
The feedback from Lightweight Solutions has been equally positive
and Michael Schäpers is full of praise: “WITTENSTEIN alpha hashelped the project to flourish and successfully assessed and incorporated several essential changes to the design – often with repercussions for the line as a whole. What’s more, receiving engineering
support from a single supplier saved us a lot of time and minimized
the risk of errors.”

The foundation has thus been laid for more Lisocore®
production lines and sustainable cooperation.

Lisocore®: More than simply light
Lisocore® is an extremely efficient, lightweight construction material made fromrenewable resources. Its outstanding properties are the outcome of a uniquedesign: at least two thin cover layers are locked firmly in place by a threedimensional core structure. Lisocore® consequently requires between 50 and 70
percent less material, and is correspondingly lighter, than conventional composite
wood panels.

The customer selected size 240 SPK+ right-angle gearheads with an integral output stage for the pivoting arm because their high performanceand torsional rigidity is conducive to precise and dynamic handling of thecover layers.

Six months on,back on his feet again

Ben Harrow has got
back his independence.
He can now take a walkagain without anyone tohelp him.

May 15, 2012 was a turning point in the life of Ben
Harrow, a Captain in the United States Army. He
was so badly wounded in action in Afghanistanthat he lost both legs. A father and a keen
sportsman, his next battle in life was against thewheelchair that threatened to be his permanent
fate: today, thanks to two prostheses, he canwalk again and play with his children. He owes his
new, independent and autonomous existence to
FITBONE®, the intramedullary lengthening nail.

Ben Harrow spent about two months in hospital as a result of his injuries before he was fit enough to start his rehabilitation. It was during
this period that he made up his mind he would “walk again one day”.
While fighting his uphill battle against the wheelchair he became anexpert in limb lengthening techniques: “I hit on the subject while surfing the net. It was something I’d never heard of before”, he explains,
looking back. “Nevertheless, I knew straight away that a FITBONE®
operation would literally put me back on my feet again.”
Pros and cons weighed up in numerous consultations
The chief outcome of his research was that artificial lower limbs canonly be individually fitted if the femur has a certain minimum length.
That wasn’t the case with Ben Harrow – the amputation had left his
right femur too short for a prosthetic leg. He therefore sought advice from various physicians – including a limb lengthening consultant in Baltimore who specializes in treatment using external fixators.
“He told me the treatment would last eight to ten months and that

twenty-four hours later, the leg has recovered
sufficiently to bear at least part of the FITBONE®
patient’s weight again and the first steps can beattempted with crutches.

Extremity correction with FITBONE®
The FITBONE® intramedullary lengthening nailfrom WITTENSTEIN intens is a fully implantable
limb lengthening system, for example for compensating leg length discrepancies or one-sided
abnormal or impaired growth. The operationby specially trained surgeons is a minimally invasive procedure which gives perfect cosmetic
results with no scarring or side-effects. Only

I’d have to take antibiotics the whole time to rule out the risk of infection”, Ben Harrow continues. Yet he refused to resign himself tothis less-than-satisfactory solution and carried on searching until
he stumbled on Dr. Mark Dahl. “He belongs to the specially trained
network of surgeons at the Centers of Excellence, whose members
benefit from the regular instruction and qualification measures weprovide in connection with FITBONE®, adds Stefanie Michel, ProductManager WITTENSTEIN intens. The physicians participating in thisnetwork are all experts in the intramedullary lengthening nail who
have helped several thousand patients achieve new mobility over the
past few years. “Definitely the most important aspect for me wasthat the FITBONE® could be fitted to my very short right femur”, Ben
Harrow points out.
The wheelchair is banished for good
The FITBONE® procedure was a huge success – as was the treatment process. “Dr. Dahl reckoned on longitudinal growth of about

They can be discharged from hospital withina few days and subsequently control the distraction process themselves in the comfort oftheir own home. They are provided with a handy
transmitter for this purpose, which activates the
FITBONE® motor and carefully lengthens the nail.
In contrast to external fixators, FITBONE® unites
high wearing and treatment comfort for the patient with significantly reduced pain throughout
the distraction phase. Another advantage isthat rather than being confined to their bed, thepatient can to a large extent lead a normal life
again during the treatment period.

five to seven centimeters to begin with, but eleven months on wemeasured an amazing fifteen centimeters – just perfect for fitting theprosthesis”, Ben Harrow recalls.

Six months later, he’s finally made it: Ben Harrow is
out and about again on two legs without anyone tohelp him. Not surprisingly, he has no reservations inrecommending the FITBONE® treatment to others. It’sa story that’s propelled him to stardom on American
TV shows and YouTube.

Helicopter performance

Active parallel flight control by
WITTENSTEIN aerospace & simulation

From rod and pulley system tosoftware control: Whereas nextgeneration helicopters haveelectronic fly-by-wire control, manyolder models that have gone into
service over the last few decades arestill equipped with electromechanicalflight control systems.
The active parallel actuator systemdeveloped by WITTENSTEIN
aerospace & simulation as a
retrofit for these helicoptersachieves a dramatic improvementin performance while significantly
reducing the outlay for repairs andmaintenance.

Experts have estimated that several thousand
electromechanically controlled helicoptersworldwide would benefit from a retrofit with theactive parallel system. “These machines weredeveloped, built and taken into service long
before the technology was ripe for electronicflight control”, explains Christoph Heine, Managing Director of WITTENSTEIN aerospace &simulation GmbH. “The pilot enters flight commands using throttles, center sticks or pedals,
for example. Their movements are transferredto the rotors by rods and hydraulic systems.
Less maintenance, degrees of freedom
safely controlled
Like any electromechanical system which
has to meet very strict loading and safety requirements, the complete actuator technology
needs a great deal of maintenance. Added tothis is the safety aspect. A helicopter has four
degrees of freedom in flight – vertical, pitch,roll and yaw; in the absence of fly-by-wire,
their respective critical regions can generally only be determined by test pilots and only
coordinated with one another to a limited extent. “This presents risks, for instance if the pilot yaws too much in forward flight”, Christoph

Heine adds. The latest state of the art puts an
end to these drawbacks. Thanks to the active
parallel solution developed by WITTENSTEIN
aerospace & simulation, the pilot’s mechanicalcontrol movement is now executed electronically. Less maintenance is necessary and thecritical regions of the four degrees of freedom
in flight can be programmed and optimally correlated in the software.
Safe use in the critical regions adds up to
more performance
The actuator system retrofit allows all assemblies with a major influence on flight performance to be electronically controlled: the main
rotor for vertical movements, the rotor swashplate for helicopter roll and pitch and the tail rotor for yaw about the helicopter’s own axis. “Allof these different types of movement together form a kind of 4D coordinate system – werefer to it as an envelope – within which thepilot can control the aircraft”, Christoph Heine
continues. “In contrast to a mechanical flightcontrol system, this envelope is protected by
the software and the active parallel actuators.”

Performance up
by max.

+20%
Retrofit boosts performance:
The active parallel actuator system
can be supplied as a retrofit andupgrade package for numerous
helicopter models.

During flight operations the pilot can thus venture into critical regions that were previously
out of reach; a helicopter equipped with thisretrofit performs up to 20% better, for example
because the payload is higher or maneuvers
more precise. “And in tricky situations, the joysticks provide the pilot with tactile feedback on
the ‘dangerous’ maneuver”, Christoph Heine
concludes.

Linear actuators with screw
New addition to the cyber dynamic line family
They’re something a lot of engineering companies havebeen yearning for: industrial grade small servo motors withan integrated screw. They’re the ideal solution for highly
dynamic positioning axes or for installation in a confined
space. When combined with the servo regulators in thesimco drive series, they can even be configured as complete
small servo axes.

They can be integrated in the appropriate automation environment
via suitable fieldbus interfaces. This new series makes a perfectcomplement to WITTENSTEIN cyber motor’s portfolio of rotary servo
motors and servo actuators in the cyber dynamic line product family.
High power density in an industry grade design
With their high power density and dynamics, the new small servo motors with integrated screw are particularly impressive in action. Eachof the four available sizes achieves excellent acceleration values, cycle rates and machine throughputs in a very small space. “This is dueto the compact design, which results in much lower mass inertia thanis possible, for instance, if the screw is simply attached to the servo
motor”, explains Carolin Ank, Product Manager at WITTENSTEIN cyber motor. The strictly industry grade design was another top priority.
The complete actuator is accommodated in a robust stainless steel
housing with IP54 protection and can be mounted in any position.
The screw itself is maintenance-free with an anti-rotation mechanismand fits inside a closed thrust tube. The spindle drive and reinforced
bearings allow both a tensile and a compressive force to be applied.
An absolute single-turn encoder system can be supplied for all sizes.
“If the 32 or 40 size is installed, the functionalities of our own, integrated multiturn encoder – probably the smallest currently on offer inthe market – can additionally be implemented as an option”, Carolin
Ank continues. All sizes are moreover designed using EMC shielded
single-cable technology which is suitable for cable carriers. “Thanks

anti-rotation mechanism

to these innovative features, the actuators are perfect for industrial
applications”, the Product Manager adds.
Open to comprehensive solutions with special connectivity
The new small servo motors with integrated screw can be configured with simco drive servo regulators to form high-performancesmall servo axes. They can be integrated in a higher-level controller via CanOpen, EtherCAT, Profinet RT/IRT or EtherNet/IP. At thesame time, this single-source system solution entails absolutely nointerface risks and has an electronic identification plate that reduces
the time for commissioning. As another software feature to simplify
start-up, two special homing modes are provided: they enable theend positions to be determined easily, safely and reliably and preventthe actuator’s mechanical stops from being approached dynamically.

In short: These maintenance-free small servo motors
with an integrated screw in the cyber dynamic line
series are ideal whenever a strictly industry grade
design, high compactness and dynamics, wideranging connectivity and optimal energy efficiency arecalled for.

More reliable and more energy efficient:
servo technology takes the place of pneumatics
Unlike pneumatic cylinders, these linear actuators with an integrated
screw permit precise, flexible and stepless position control regardless of the application – without any retooling on the machine. They
thus have a clear advantage in applications where frequent formatchanges are likely. The servo technology offers better controllability by design; together with the easy connection to a higher-level
controller, this facilitates reproducible processes. A linear actuator– and indeed the entire servo drive technology – eliminates the riskof leakage at the compressed air line. It is also more energy efficient – after all, compressed air is not only expensive to produce but
a significant share of it is lost. Finally, servo technology is virtually
maintenance-free and also quieter – two further benefits comparedto pneumatics.

All-rounders
for the engineering industry
These maintenance-free small servo motors with an integrated screw
open up a range of exciting solutions. They are used, for instance, forpositioning, joining, bending, gripping and dispensing in reshaping
and handling applications, the semiconductor industry, packaging
machinery or assembly automation. The 100% stainless steel design
with IP65 protection also creates numerous interesting applications
for the new, integrated linear actuator in food and beverage plants,
such as in filling valves for highly precise bottling lines.

WITTENSTEIN SRL has been producing in
Sura Mica, not far from Sibiu (Romania) since2008. A total of 57 people meanwhile work at
the plant there. “It wasn’t easy finding qualified
staff to begin with”, recollects Markus Rothenfels, Managing Director of WITTENSTEIN SRL
in Romania. “Traineeships in industry still don’t
enjoy a very good reputation among the population, not least because the state-run educational institutions are poorly equipped andmany Romanian companies really do give theimpression of being relics from another age.” It
was soon clear to both him and Dr. Felix Szabo,
his Head of Production, that in the long term
it would not be possible to meet the demand
for specialists without actively providing training locally.

Training “made in Germany”
Highly qualified specialists are a rarity in many
countries. The German dual model of vocational
training is the object of worldwide envy andadmiration because it guarantees a high standardof training for young people that is geared to actual
needs. At its international manufacturing locations,
WITTENSTEIN sets great store by a training
concept based on the German idea of theory andpractice closely interwoven: the first young industrial
mechanics, toolmakers and mechatronics fitters in
the U.S. and Romania will soon be completing theirapprenticeships.

Building bridges together
An important role when exporting educationis played by any training establishments which
already exist as well as by other German companies in the country concerned or – whereapplicable – the German Chamber of Commerce. “We are co-initiator of a new, three-year
ICATT program (Industry Consortium for Advanced Technical Training) by AHK USA (German-American Chamber of Commerce)”, says
Peter Riehle, President and CEO of the WITTENSTEIN holding, Corp. in Bartlett / Chicago. AHK Chicago, the State of Illinois, German
SMEs and U.S. firms have set up this program
to enable young people to train as an industrial
mechanic. In addition to the school based part,
apprentices also receive practical training fromtheir respective employers. Today, Manager
Training Jürgen Limbrunner looks after three
aspiring industrial mechanics at the WITTENSTEIN Training Workshop.
Laptop donation to vocational training
college
Adapting German training standards to country-specific realities – this step-by-step strategy is being pursued with a considerable
measure of success in Romania. Three WITTENSTEIN trainees in their first year and four
more in both the second and third years are
already benefiting from specialist instructionin CNC machine operation and mechatronics
at ‘Independenta Sibiu’ vocational training college. The project was initiated by Sibiu’s German-Romanian Dual Training Association, of
which WITTENSTEIN Head of Production Dr.
Felix Szabo is Vice President. WITTENSTEIN
regularly assists with renovation work andcollege equipment through donations in cash
and kind – for example with 20 new laptops for

IT training. In the meantime, the subsidiary’s
own in-house training has been brought intoline with the WITTENSTEIN standard: there
are specific curriculae and a typical WITTENSTEIN training island – an electrical workbench
including turning and box-column drilling machines.
Same standards worldwide“We want to ensure the same high quality
elsewhere in the world as we have in Germany” – this is what Dr. Kathrin Heckner, Manager Training at WITTENSTEIN SE, is aiming for.
That also includes training the next generationof specialized staff ourselves. “It’s the only way
we can meet our own technical and commercial requirements. And in addition to training
qualified specialists, we also want to fulfil oursocial responsibility in each country where we
operate. Integrating apprentices and vocational training into the everyday life of the company simultaneously creates added value for our
corporate professional development culture in
general – if we can succeed in communicating
the necessary technical and process expertiseto young trainees, we’ll be just as good andefficient in that respect when it comes to our
future employees.”
Pioneering work in Romania and the U.S.
Markus Rothenfels knows that untiring perseverance is a must: “By investing in training
both at educational institutions and in-houseat companies, we gradually make gaining
qualifications in this kind of profession more
attractive for the local population. This is not
something that will happen overnight and we
can’t afford to take it for granted. Here in Transylvania, for instance, we organize careers caravans at schools to put young people directly
in touch with potential employers.
The project initiated by Peter Riehle and his
fellow-entrepreneurs in Chicago is likewisereaching a growing number of people: theGerman-American Chamber of Commerce iscurrently extending its training program to Wisconsin, Michigan and Indiana. And the ICATT
standards have also been taken up in equivalent programs in Atlanta and New York. Training “made in Germany” is a genuine export hit.

»Qualiﬁed specialists are scarce inthe U.S., which is why we’re actively
involved in the ICATT program in
Chicago. The dual training format
doesn’t only work for German companies
in the States – there’s also a hugeinterest on the part of American ﬁ rms.«

Close to the customer,
prompt service in Northern Europe

20 years of WITTENSTEIN Sweden / Denmark
The WITTENSTEIN Group’s Scandinavian
subsidiary recently celebrated its 20th anniversary in Malmö (Sweden). Ever since it was firstestablished in 1996, customers in Sweden and
Denmark have profited from a broad array ofcompetencies, products and system solutions.

Employees as the key to success
There is no doubt in the mind of Björn Proschinger, Head of Sales Europe, WITTENSTEIN alpha GmbH: “Our customers value theexpertise and the absolute customer focus of
the entire WITTENSTEIN team in Sweden and
Denmark very highly. That’s one reason why
such close and enduring relationships havebeen built up with their key contacts over many
years.”
Eight staff testify to the Scandinavian subsidiary’s remarkable growth since the original “alpha drives” was founded. In the last 20 years
only two people have left the team headed by
Managing Director Johan Sjölin. He sees trust,
continuity and cohesion – not just among theemployees – as the key drivers of steady andsustainable growth: “It’s important in sales
to maintain a local presence and be close towhere your customers are. That’s especiallytrue if you’re selling technical products whose
success depends on designs and concepts
tailored to individual needs. The closer we areto our customers, the less time it takes us to
optimize their mechatronic solutions and improve the performance of their machines”.

WITTENSTEIN’s share of the Scandinavian
market to more than 60%. The high level ofautomation expertise and the ability to implement the most diverse customer requirements
rapidly were crucial here. “We respond to inquiries immediately. It goes without sayingthat we endeavor to keep delivery times toa minimum. That strengthens our position in
the market and helps us generate new leads”,
Johan Sjölin explains. It’s no wonder that Scandinavia’s number one manufacturer in the foodand beverages industry names WITTENSTEIN
Sweden / Denmark as their preferred supplier.

that lie ahead, and will in future have extra
space available to handle them. It was with thisin mind that WITTENSTEIN Sweden / Denmark
moved to a new location in March 2017 – forthe fourth time in the company’s history. The
new premises are better aligned to the needsof both customers and staff. The Scandinavian
subsidiary HQ has remained true to its roots
in southern Sweden. After all, continuity andcloseness to the customer are attributes worth
preserving.
