3-phase-asynchronous-motors for frequency inverter operation

In order to change the engine speed of a 3-phase asynchronous motor it has to be equipped with a frequency inverter. The frequency inverter ensures that the applied voltage is always in a certain proportion to the frequency.

Due to the high switching frequencies of the frequency inverter high demands are made to the isolation of the motor and the layout of the magnetic circuit. Our product range is tuned for these requirements.

With the help of a frequency inverter and speed feedback the speed regulation characteristic of the 3-phase-asynchronous motor has an almost linear correlation between applied voltage and the speed of the motor.

In order to allow also the adjustment of highly dynamic processes, it is necessary to adjust the frequency inverter to the motor
