General technical information

3.1

Product description

The drum motor is a completely enclosed electrical drive roller. It replaces external components such as motors andgears, which require frequent maintenance.
The drum motor can be used in environments with high coarse and fine dust exposure as well as exposed to water jets
and spraying water and is resistant to most aggressive ambient conditions. In harsh environments and environmentswith salt water, only stainless steel motors should be used. Thanks to its protection rating of IP66 and its stainless steel
design (upon request), the drum motor is also suitable for use in the food processing and pharmaceutical industries, aswell as for applications with high hygienic demands. The drum motor can be used with or without a drum coating toincrease friction between drum motor and conveyor belt, or with a profile coating to drive form-fit driven belts.
DL series drum motors are driven by an asynchronous three-phase induction motor. That motor is available atdifferent power levels and for most international supply voltages.
The drum motor contains oil as lubricant and coolant which dissipates the heat via the drum shell and the conveyor
belt.
Integrated thermal overload protection
A thermal circuit breaker integrated in the winding head protects against overheating. The switch trips if the motor
overheats. However, it must be connected to a suitable external control device that interrupts the power supply to themotor in case of overheating.

3.2

Dimensions

Some dimensions are listed as „FW+”. FW is the abbreviation for „Face Width” (drum width). This information is
located on the type plate of the drum motor.
All length-related dimensions in the catalog and in these operating instructions comply with the requirements of DIN/
ISO 2768 (medium quality).
The recommended distance between the mounting brackets (EL) while taking into account the maximum
thermal expansion and internal tolerances is EL + 2 mm.

Thermal protection

Under normal operating conditions, the thermal circuit breaker integrated in the stator winding is closed. When the
motor limit temperature is reached (overheating), the switch opens at a preset temperature to prevent damage to themotor.

WARNING
The thermal circuit breaker is automatically reset after the motor has cooled off.
Inadvertent start-up of the motor¾

Connect the thermal circuit breaker in series with a suitable relay or contactor so that the current supply tothe motor is safely interrupted when the switch trips.

¾

Ensure that the motor can be switched on again after overheating only with a confirmation button.

Type plate of DL series asynchronous 3-phase

The information on the type plate of the drum motor is used to identify it. This is the only way for the drum motor to
be used properly.
Drum motors of the DL series have different kinds of type plates:
1.

Round type plate (1) on the end housing of the drum motor (glued or laser-engraved)

2.

Rectangular type plate (2) on the terminal box (if available, glued or laser-engraved)

3.

Rectangular type plate (3) included with the motor

Available motor torque in %Value 1: Based on a rated motor frequency of 50 Hz (50-Hz motors should be operated only up to 70 Hz in the
speed range under field control.)Value 2: Based on a rated motor frequency of 60 Hz (60-Hz motors should be operated only up to 80 Hz in the
speed range under field control.)The torque dependency depicted in the figure above is expressed as P = T x ω. With a reduced operating frequency
of below 20/24 Hz, the motor torque is reduced by changing heat dissipation conditions. The power loss dissipation isa result of the oil quantity, in contrast to standard ventilated motors. For frequencies starting at 80 ... 85 / 95 100 Hz,
the curve for the output torque does not have a hyperbolic shape, but is instead replaced with a quadratic function
which is the result of the effect of the pull-out torque and the voltage. The output/ frequency characteristics of mostfrequency inverters supplied with 3 x 400 V / 3 x 460 V can be parameterized to 400 V / 87 Hz in order to connect
motors with 230 V / 50 Hz. This may create further losses in the motor and lead to its overheating if the motor isdimensioned with insufficient power reserves.

Clock frequency:
A high clock frequency leads to a better utilization factor of the motor. Optimum frequencies are 8 or 16 kHz.
Parameters such as the quality of smooth running tests (motor is running smoothly) and noise development are also
affected positively by high frequencies.

Asynchronous drum motors with frequency inverters
Voltage increase:
Interroll Drum Motors are generally suitable for operation on frequency converters and therefore also for high rates
of voltage rise.
Nevertheless, high rates of voltage rise in conjunction with long motor cables cause high pulse voltages which stressthe insulation system and cause it to age. To prevent premature ageing of the winding insulation and thus damage tothe drum motor, motor chokes, dU/dt filters or sine filters can be installed between the inverter and the drum motor.
Please refer to the operating instructions of the frequency inverter for the recommended cable length.
Voltage:
If a frequency inverter with single-phase supply is installed in the drum motor, the specified motor must be designed
for the frequency inverter output voltage and must be connected accordingly. Single-phase motors cannot be
operated with a frequency inverter.
Output frequency:
Applications with output frequencies in the speed range under field control above 70 Hz should be avoided (forasynchronous motors only). High frequencies can cause noise, vibrations and resonances, and reduce the rated output
torque of the motor.
With 87-Hz technology, asynchronous motors can be operated up to a maximum frequency of 87 Hz. However, at 87
Hz, the motor must not consume more power than specified on the type plate of the motor. 87-Hz technology requires
a motor that has at least 75 % power reserves during 50-Hz operation. Caution should be exercised when using
V/f-regulated inverters with frequencies below 20 Hz since doing so could result in overheating or power loss of the
motor. For information about required power reserves, contact your local Interroll dealer.
Motor output:
Not all frequency inverters can run motors with more than 6 poles and/or output powers below 0.2 KW/0.27 PS. If in
doubt, please contact your local Interroll dealer or the supplier of the frequency inverters.
Frequency inverter parameters:
Frequency inverters are usually delivered with factory settings. Given these settings, the inverter is generally not
immediately ready for operation. The parameters must be adjusted to the corresponding motor. For frequency
inverters sold by Interroll, startup instructions for the corresponding frequency inverters that were specifically createdfor drum motors can be supplied upon request.

Belt tension

The following must be observed when calculating the belt tension:• Length and width of conveyor belt
• Belt type• The belt tension required for transporting the load
• The belt elongation required for the assembly (depending on the load, the belt elongation for the assembly shouldmeasure between 0.2 and 0.5 % of the belt length)• The required belt tension must not exceed the maximum belt tension (TE) of the drum motor.
The values for the belt tension and elongation are available from the belt manufacturer.

The required belt tension T1 (top) and T2 (bottom) can be calculated according to the specifications of DIN 22101 or
CEMA. Based on the information from the belt manufacturer, the actual belt tension can be roughly determined by ameasurement of the belt elongation during tensioning.
The maximum permissible belt tension (TE) of a drum motor is listed in the drum motor tables of the catalog. Belt type,belt thickness and drum motor diameter must match the information from the belt manufacturer. If the diameter of thedrum motor is too small, it can lead to damages to the belt.
If the belt tension is too strong, it can damage the shaft bearings and/or other internal components of the drum motorand shorten the service life of the product.

8.4.1

Belt elongation

The belt tension is created by the force of the belt when it is stretched in longitudinal direction. To prevent damages tothe drum motor, it is absolutely necessary to measure the belt elongation and to determine the static belt tensioning
force. The calculated belt tension must be equal to or lower than the values specified in the drum motor tables of thecatalog.

Drum coating

A drum coating (e.g. rubber coating) that was applied retroactively can cause the drum motor to overheat. For somedrum motors, there may be restrictions concerning the thickness of the drum coating.
To avoid a thermal overload, the required output should be multiplied with 1,2.
Please contact Interroll concerning the type and maximum thickness of a drum coating if you want to apply
one.

8.6

Sprockets

To operate link belts with sprockets requires that a sufficient number of sprockets are attached to the drum shell inorder to support the belt and to correctly transfer the force. Sprockets that engage with the belt must have a floating
fit to prevent them from interfering with the thermal expansion of the belt. Only one sprocket may be affixed for belt
guidance; as an alternative, the belt may also be guided at the sides.
For a belt guidance with fixed sprocket, the number of sprockets should be odd so that the fixed sprocket can bearranged in the center. At least one sprocket should be used for every 100 mm belt width. The minimum number ofsprockets is 3.
The force is transferred using a key steel welded onto the drum shell. In general, this key steel is 50 mm shorter than
the tube length (SL).
