Version 1.3 (09/2016) en-US
Original instruction manualInterroll Drum Motor C Series, S-SMP Series, S Series DC

Product information
Product description
The drum motor is a completely enclosed electrical drive roller. It replaces external components,
such as motors and gear boxes that 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 of the aggressive ambientconditions. Thanks to protection classification IP66 or IP69k and its stainless steel design (uponrequest), the drum motor is also suitable for use in the food processing industry andpharmaceutical industry, as well as for applications with high hygienic demands. The drum motor
can be used without and with a rubber lagging to increase the friction between drum motor andconveyor belt, or with a profile coating to drive modular or profile belts.
The drum motors of the C and S-SMP series are driven by an asynchronous AC induction motor.
It is available in different power stages and for most of the international supply voltages.
Drum motors of the S-DC series are driven by a 24-V DC brush motor.
The drum motor contains oil as lubricant and coolant which dissipates the heat via the drum shelland the conveyor belt.
If a drum motor without belt or with a modular belt is used, a special design is available toensure cooling.

Version 1.3 (09/2016) en-US
Original instruction manual

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 has to beconnected to a suitable external control device that interrupts the current supply to the motor incase of overheating (see "Thermal protection", page 29).

Dimensions
Some dimensions are listed as "SL+". SL is the abbreviation for "shell length" (tube length). Thisdimension can be derived from the RL data on the type plate of the drum motor (see "Type plateof drum motor", page 11). For drum motors 80S and 113C, the RL dimension is identical to the
FW data.
• For drum motors 80C/80S-SMP/80S DC: SL = RL - 10
• For drum motors 113C/113S-SMP/113S DC: SL = RL - 22

Value 1: based on motor rated frequency 50 Hz
Value 2: based on motor rated frequency 60 Hz
The torque dependency depicted in the figure above is expressed as P = T x ω. At a reduced
operating frequency of below 20/24 Hz, motor torque is reduced by changing heat dissipation
conditions. The power loss dissipation is a result of the oil quantity, in contrast to standard fan
motors. For frequencies starting at 80- 85/95- 100 Hz, the curve for the output torque does nothave the hyperbolic shape indicated above, but is instead replaced by a quadratic function thatis the result of the effect of the pull-out torque and the voltage. The output/frequency
characteristics of most frequency inverters supplied with 3 x 400 V/3 x 460 V can beparameterized to 230 V/50 Hz in order to connect 230-V motors. This causes further losses in
the motor and leads to its overheating.

Frequency inverterparameters

28• 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 smooth running test quality(motor is running smoothly) and noise development are also affected positively by highfrequencies.
• Voltage increase: Interroll motor windings are dimensioned for a rated voltage increase
rate of 1 kV/μs. If a frequency inverter generates a steeper voltage increase, motor chokes
can be installed between frequency inverter and motor. But since all drum motors fromInterroll run in an oil bath, the risk of overheating or damage to the motor due to large
voltage increases is extremely low. If in doubt, please contact your local Interroll dealer.
• Voltage: If a frequency inverter with single-phase supply is installed at the drum motor, it
must be ensured that the specified motor is dimensioned for the supply voltage used and isconnected accordingly!
• Output frequency: Caution should be exercised for applications with output frequencies
above 87/100 Hz. High frequencies can cause noise, vibrations and resonances, and reduce
the rated output torque of the motor. Caution should be exercised when using inverters withfrequencies below 25 Hz since this could result in overheating or power loss of the motor. If
in doubt, please contact your local Interroll dealer.
• Motor output: Not all frequency inverters can operate motors with more than 6 poles and/or output powers below 0.2 KW/0.25 HP. 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 a standard
parameter set. This allows the inverter to be used immediately. However, the standard
parameters may not be optimally set for your motor and may have to be adjusted to thespecific motor.

Thermal protection
Under normal operating conditions, the thermal circuit breaker integrated in the stator winding isclosed. When the motor limit temperature is reached (overheating), the switch opens at a preset
temperature (depending on the insulation class of the winding) to prevent damage to the motor.

WARNING
The thermal circuit breaker is automatically reset after the motor has cooled off.
Inadvertent start-up of the motor
4 The thermal circuit breaker must be connected in series with a suitable relay or contactor sothat the current supply to the motor is safely interrupted when the switch trips.

Assembly and installation

NOTICE
Damage of the drum motor from incorrect power supply
4 Do not connect an AC drum motor to an excessively high DC voltage supply and a DC drum
motor to an AC voltage supply – this will lead to irreparable damages.
4 Do not connect drum motors of the D-series directly to the supply system. D-drum motors
must be operated via suitable frequency inverters or servo drive controllers.

Electrical connection of the drum motor
Connecting the drum
motor – with a cable

4 Ensure that the motor is connected to the correct supply voltage according to the motor typeplate.
4 Ensure that the drum motor is correctly grounded with the yellow-green cable.
4 Connect the motor according to the connection diagrams (see "Connection diagrams for C
series", page 24).

Single-phase motor

If a starting torque of 100% is required, single-phase drum motors,should be connected to astarting capacitor and a run capacitor. An operation without starting capacitor can reduce thestarting torque to 70 % of the rated torque listed in the Interroll catalog.
Interroll recommends the use of capacitor type class B 10,000 hours / 450 V according to EN
60252.
Connect the starting capacitors according to the connection diagrams (see "Connection diagramsfor C series", page 24).

External motor protection

The motor must be protected by a suitable fuse or other external protective device. The
protective device must be set to the rated current of the corresponding motor (see type plate).
The voltage supply must be protected against a potential counter EMF. The motor generates a
counter EMF if an external force acts upon it.
4 Install one overload protection for each motor. Such a protection can consist of, e.g. a slow
fuse, a circuit breaker or a current limiter.

Integrated thermal
protection

CAUTION
Accidental motor start
Crushing hazard for fingers
4 Connect the integrated thermal circuit breaker to an external control device that interrupts
the current supply to the motor at all poles in case of overheating.
4 After the thermal circuit breaker has tripped, examine and remove the cause for overheating
before the current supply is reactivated.

Assembly and installation

For operational safety, the motor must be safeguarded against overload with an external motor
protection, as well as an integrated thermal protection; otherwise, there is no warranty if the
motor fails.
Frequency inverter

Asynchronous drum motors can be operated with frequency inverters. Frequency inverters fromInterroll are general adjusted to factory setting and have to be parameterized for the respective
drum motor. For this purpose, Interroll can supply parameterization instructions. In this case,please contact your local Interroll partner.
4 If no frequency inverter from Interroll is used, the frequency inverter must be correctlyparameterized according to the specified motor data. Interroll can provide only very limited
support for frequency inverters that are not being sold by Interroll.
4 Resonance frequencies in the power supply line must be prevented since the create voltage
spikes in the motor.
If the cable is too long, frequency inverters generate resonance frequencies in the line
between frequency inverter and motor.
4 Use a completely shielded cable to connect the frequency inverter to the motor.
4 Install a sine-wave filter or a motor choke if the cable is longer than 10 meter or if afrequency inverter controls several motors.
4 Ensure that the cable shield is connected to a grounded part according to theelectrotechnical guidelines and local EMC recommendations.
4 Always observe the installation guidelines of the frequency inverter manufacturer.
