Description

Motor reactors reduce the voltage stress on the motor windings by reducing the voltage
gradients at the motor terminals that occur when motors are fed from drive converters. At the
same time, the capacitive re-charging currents that additionally load the output of the Power
Module when longer motor cables are used are simultaneously reduced.

Safety information

Caution
The cooling clearances of 100 mm above and below the components must be observed.
Note
The connecting cables to the Power Module must be kept as short as possible (max. 5 m).
Caution
When using motor reactors that SIEMENS has not approved for SINAMICS, then these can
thermally damage the reactor.
Caution
The surface temperature of the motor reactors can exceed 80 °C.
Caution
The maximum permissible output frequency when motor reactors are used is 150 Hz.
