Group drive of asynchronous motors
A group drive is a group of asynchronous motors of any power rating. The motors do not have a rigid mechanical connection or only have a connection that is subject to slip and are connected to an electrically parallel inverter.
After a suitable startup, operation is possible.
If motors with different power ratings are operated at the inverter in parallel, the motor with the largest power rating has to be set up.
- The total of the motor currents must not exceed the nominal output current of the inverter.
The maximum number of motors depends on the control mode:
Control mode | Number of motors |
|---|---|
LVFC | 64 |
