Modern technology for the energy transition

In offshore wind farms, technical drives are exposed to severe environmental conditions. Salt water, wind and salt spray place extreme demands on all components used. Owners of such a system must nevertheless ensure reliable and fail-safe operation.

This is exactly where the KOSTAL drive controllers from the INVEOR series come into play: the devices perform even at temperatures of -25 or +50 degrees. Such temperature ranges are not uncommon for wind turbines. In addition, the salty air cannot harm our INVEOR variable frequency drives. We have designed the variable frequency drives to be totally resistant to salt spray. KOSTAL technology is therefore also ideally suited for use on the high seas.

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.

Because renewable energies will play an increasingly important role in the future, KOSTAL is focusing more and more on the research and development of impressive and economical variable frequency drive technology. INVEOR drive controllers from KOSTAL ensure maximum performance, smart use of energy and more productivity in renewable energy generation.

Various INVEOR models ensure that you find exactly the right KOSTAL product for each individual application. With variable frequency drives from KOSTAL, you have the ideal device on board in the field of renewable energies.
