Abstract:
An arrangement for detecting a direction of rotation of a multi-phase electric motor includes a plurality of single-phase converters. Each single-phase converter of the plurality of single-phase converters supplies one phase of the multi-phase electric motor with current. The arrangement also includes two sensor units that are configured to determine actual values of the phase currents of the multi-phase electric motor and to transmit the actual values to the plurality of single-phase converters. The arrangement also includes a monitoring and control unit in each converter of the plurality of single-phase converters. The monitoring and control unit is configured and programmed to determine the direction of rotation and a speed of rotation of the multi-phase electric motor from the actual values.
