For the INVEOR, usage in modern wind turbines is not limited to roller bearing drives for azimuth and pitch adjustment, but they can also be used for a variety of hydraulic applications in this environment, such as in the area of pitch adjustment, azimuth braking, rotor braking and locking. All these hydraulic pumps can be controlled by the INVEOR. Another area of application for the INVEOR is high-performance cooling for these stationary hydraulics using appropriate oil fans.
Another KOSTAL plus point: our power electronics for roller bearing drives and hydraulic pumps require no electrolytic capacitors whatsoever. This makes KOSTAL variable frequency drives significantly more robust than comparable models with electrolytic capacitors. Our INVEOR variable frequency drives can therefore withstand much higher vibrations. As motor-mounted variable frequency drives, our devices can handle loads of up to 5G.
