General technical information
3 General technical information
3.1 Product description
The drum motor is a completely enclosed electrical drive roller. It replaces external components such as motors and
gears, which require frequent maintenance.
Thedrummotorcanbeusedinenvironmentswithhighcoarseandnedustexposureaswellasexposedtowaterjets
and spraying water and is resistant to most aggressive ambient conditions. In harsh environments and environments
with 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, as
well as for applications with high hygienic demands. The drum motor can be used with or without a drum coating to
increasefrictionbetweendrummotorandconveyorbelt,orwithaprolecoatingtodriveform-tdrivenbelts.
DL series drum motors are driven by an asynchronous three-phase induction motor. That motor is available at
dierent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.
3.1.1 Options
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 the
motor in case of overheating.
3.2 Dimensions of DL series drum motor
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.

General technical information
3.5 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 the
motor.
WARNING
The thermal circuit breaker is automatically reset after the motor has cooled o.
Inadvertent start-up of the motor
¾Connect the thermal circuit breaker in series with a suitable relay or contactor so that the current supply to
the motor is safely interrupted when the switch trips.
¾Ensurethatthemotorcanbeswitchedonagainafteroverheatingonlywithaconrmationbutton.
¾Aftertheswitchhastripped,waituntilthemotorhascooledo,andensurepriortoswitch-onthatthereis

4.3 Connection diagrams of DL series asynchronous 1-phase
This instruction manual lists only standard connection diagrams. For other connection types, the connection diagram is
supplied separately with the drum motor.
Abbreviations see page 56.
4.3.1 Cable connections
1-phase, 6-core cable
* A starting capacitor and a matching switching relay can be connected as an option to improve the starting torque
of the single-phase motor.

5.1 Type plate of DL series asynchronous 3-phase
The information on the nameplate of the drum motor is used to identify it. This is the only way for the drum motor to
be used properly.

1. Round nameplate (1) on the end housing of the drum motor (glued or laser-engraved)
2. Rectangular nameplate (2) on the terminal box (if available, glued or laser-engraved)
3. Rectangular nameplate (3) included with the motor
