Custom 

 Motors

A Custom Approach 

Since 1920

	 Since our beginning in

1920, Baldor has earned a

reputation throughout the world

as a designer, marketer and

manufacturer of the highest

quality, most reliable electric

motors you can find anywhere.

Baldor has been a key partner

to equipment designers,

consulting/specifying engineers,

plant maintenance, repair and

operations personnel. Every day

we design and manufacture

a large variety of custom

motors. In fact, our custom

motor designs exceed 100,000

different specification types.

Any Application 

Any Spec

	 Whether you

need special

flange, foot or

face-mount

configurations,

custom shafts,

special windings

and performance

requirements...

even custom

colors and

nameplates,

you spec it and

Baldor can build

it. With decades

of experience as

product development partners

with our customers, you can

count on Baldor.

We Build Them 

Your Way...FAST!

	 And, because we know

you can’t wait forever to

get them, Baldor guarantees

the fastest delivery in

the industry. In fact, your

custom motor order will

typically be shipped to you

A

Custom Approach

to Custo m M otors
	 We start with reviewing

what YOU need. After all, it is

your application. From an array

of enclosures, finishes,

colors, mountings,

windings, shafts...

the list of custom

features

available

is almost

unlimited. Rapid

prototypes and extensive

testing of every Baldor custom

motor are two other reasons

why Baldor custom motors

consistently exceed our

customer’s expectations.

	 We can’t possibly list all

the customization features

we can perform for your next

project. But we can give you

a general idea of the type of

custom work we perform

everyday. Contact us to

discuss your particular

custom motor challenge

and see for yourself why

Baldor is

the custom

motor leader.

Custom

motors built

the way you

want them, when you want

them. That’s the Baldor way!

Custom Colors and 

Finishes

Baldor is able to supply motors 

in practically any color, shade or 

finish. Just provide the color you 

want and we’ll match it. Hammer 

tone, epoxy finishes or food grade 

paints are also available.

Enclosures

Motors are available in Totally Enclosed Fan 

Cooled, Totally Enclosed Non-Ventilated, Totally 

Enclosed Air Over, Totally Enclosed Blower 

Cooled, Explosion Proof and Open Drip Proof. 

Stator housings are available in cast iron, 

stainless steel, steel and extruded aluminum. 

Weather Protected Type I and II are also 

available on above NEMA frames.

Base Mounts

In addition to the standard NEMA mounting, IEC metric, 

pre-1964 and pre-1952 NEMA mountings can be produced. 

We also manufacture numerous sidewall and ceiling mount 

designs. Unique mounting configurations can be developed to 

match your specs.

Conduit Box

Conduit box location can vary 

depending on your application. 

Terminal blocks can be provided. 

Special boxes for Explosion Proof, 

Severe Duty and Washdown 

applications are also available.
Mounting Configurations

Numerous face mounting designs are available including standard NEMA C 

or D flanges as well as P base designs. Metric faces and flanges can also 

be ordered. Other mounting types include hydraulic two and four bolt pump 

mounts, square flange pump mounts and close-coupled pump mounts. 

Custom variations on any of the listed mountings can be performed.

Windings

Part winding, start, wye-delta, multi-speed and other 

special winding configurations, in 50 or 60 Hz are 

available. Special winding protection includes vacuum 

pressure impregnation (VPI), epoxy encapsulation, 

tropicalization and weatherproofing. Power cords with 

plugs, connectors, or special lengths and lead colors 

are available.

Bearings

Open, single shield, double shield or sealed bearings can be provided. 

Depending on your application, rolling element bearings (ball, roller, 

thrust or sleeve bearings) may be available. All bearing choices can be 

provided with standard temperature, low temperature, high temperature, 

food grade or customer supplied grease. Thermocouples added to the 

bearing housing or BTDs (bearing temperature detectors) can be included.

Shafts

Baldor has designed and manufactured custom shafts in over 30,000 different 

configurations. Motor shafts can be designed to fit applications requiring special 

lengths, diameters, materials or custom machining. A few other custom shaft 

features available include: flats on shafts, threads, drilled and tapped holes, tang 

shafts, tapered shafts, and shafts requiring internal or external splines. Motors can 

be ordered in double shaft configurations with custom machining on both ends. 

Shaft materials include many types of steel alloys including stainless steel.
Custom Solutions

	 Baldor excelled in designing

and producing a special motor to

power reverse osmosis equipment

used on ships to transform

seawater into fresh water. The

application required a motor that

would not stress the load of the

generators on the ship as the

water treatment equipment ran.

Baldor engineers determined a

high torque, low starting current

motor was the answer. Our

engineering group developed

new winding and rotor designs

to meet the customer’s needs.

After extensive testing, a custom

motor with a unique rotor slot

geometry was produced. This

new design reduced the inrush

current of the motor at startup

while providing the required

torque...all without affecting the

onboard generator performance.	

	 Baldor engineers provided a

solution for an OEM who asked

us to develop a custom motor for

use on their 300+ ton payload

mining trucks. These trucks are

driven by electric motors on each

wheel. The customer needed a

way to dissipate heat caused

from regeneration of electricity

when the trucks were braking.

The motor also had to handle

constant vibration during the time

the truck was in motion. Baldor

designers created a custom 100

Hp DC motor to power a fan

that cooled load resistors as

the truck brakes were applied.

Special high strength bolts were

incorporated into each motor to

hold the field coils in place and

protect against vibration. The

field and interpole coils, as well

as the motor armature, were

vacuum pressure impregnated to

protect from constant on the job

contaminants. Special insulation

was used to combat high voltage

spikes and epoxy paint was

applied inside and out to resist

rust and corrosion.

	 Baldor designers used their

expertise and experience to

design and produce a 700 Hp

motor for an OEM to power a fan

inside the high heat environment

of their autoclaves. The motor

shaft had to operate in the

extreme heat produced by the

autoclave and the motor itself

had to operate in very high

ambient temperatures for

extended periods of time.

Working closely with the local

Baldor office and the OEM, our

engineers designed a premium

efficient Super-E® motor with a

22-inch long stainless steel

threaded shaft to drive the

blower fan inside the autoclave.

Special high temperature grease,

insulation and thermocouples

were designed into the motor

along with 7-foot long power

leads to enable the motor to

operate in the area of the

autoclave.
