Frequency converters

We develop and distribute frequency converters for motor control. These are suitable for different motor topologies such as induction motor, permanent magnet synchronous motor, etc. Our frequency converters range from systems for small drive technology in the range of a few watts and 12 volts to several hundred kilowatts.


A special highlight are our frequency converters for operating multi-phase machines which can be used for various applications. With these converters, you benefit from multiple advantages, including reliability through operation of partial motors but also loss reduction and hence increased efficiency.
