10 Motor data
10.1 Motor data rated point 50Hz
( Æ Adjustment range 1:5)
a) 230V frequency inverter
The motor used for 50 Hz operation can be operated up to its rated point 50 Hz/230V 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
230 V when the frequency is increased above 50 Hz. Because of the mains voltage, maximum 230 V are
available.
The following data is based up to an output of 2.2 kW using a 230/400 V motor winding.
