inverter

The motor used for 50 Hz operation can be operated up to its rated point 50 Hz/400V with the nominal torque.
Operation over 50 Hz is still possible, however the torque output reduces in non-linear form (see diagram
below). Above the rated point, the motor enters its field weakening range, as the voltage cannot be raised over
400V when the frequency is increased above 50 Hz. Because of the mains voltage, maximum 400V are
available.
The following data is based on an output of 2.2 kW using a 230/400 V motor winding. 400/690 V windings are
used for 3 kW and higher.
