Dynamic, accurate & reliable: KOSTAL variable frequency drives for roller bearing drives

In modern wind turbines, electric motors are used in the azimuth drives, which align the turbine house perfectly with the wind. Depending on the size of the turbine, up to eight geared motors drive these roller bearings. Synchronous control and even distribution of power to all motors are particularly important here.

With the KOSTAL INVEOR MP variable frequency drive, you get an excellent control unit for azimuth roller bearing drives. The design of the variable frequency drive allows a direct connection to the motor. Once installed, it forms a fixed unit with the roller bearing drive via the adapter plate.

The absence of electrolytic capacitors in the INVEOR's power electronics as well as its control technology, which features no sensors at all, guarantees reliable and low-maintenance operation in this environment.
