The motors are not designed for direct connection to the three-phase system but have to be operated via an
electronic converter. Direct connection to the system may destroy the motor.
Winding, insulation system
The insulation materials we use ensure insulation class 155(F) to DINEN60034. Therefore, the winding temperature rise
may be max. 105K at a coolant temperature of +40°C. We also use insulation materials with the temperature profile TI200
of class 180(H) to increase the reliability of the motors.
The insulation system of the motors is designed such that they can be connected to a converter with a maximum d.c. link
voltage U
link
max. up to max. 700Volt.
Note: U
link max.
is the maximum value of the d.c. link voltage which is only transient and approximately equivalent to the
inception voltage of the braking chopper or of the energy recovery unit.
The maximum permissible rate of voltage rise (dU/dt) at the motor terminals may be max. 4kV/µs. The overvoltage at the
motor terminals must not exceed 1.56kV. It may be necessary to use motor current filters or reactors to achieve these
values.
Separately driven fan
The motors DUF are forced-air-cooled by an axial fan. The connection data are given on the motor nameplate. The necessary ter-
minal plug is included in the delivery of the motor.
Conductor size
The recommended values for the dimensioning of the conduc-
tor cross-sections are given in the table. They are specified in
DIN VDE 0113 (EN 60 204) "Electrical equipment of industrial
machines" for the current carrying capacity of PVC-insulated
cables with copper conductor routed in cable ducts. The maxi-
mum permissible ambient temperature is +40 °C.

The DUM6 motors are equipped with 2-pole resolvers, size 15, for speed and shaft position control..
Speed and shaft position measuring system/resolver
The measuring system of synchronous motors (DUM6) must be adjusted to the respective converter. Any mis-
adjustment may lead to uncontrolled motor response or complete failure of the motor.
Note:
2-pole resolvers are installed as standard. Other resolver pole numbers or other measuring systems are available
(e.g. absolute sine-cosine encoders).
