A frequency converter is an electronic device used to adjust the speed of an asynchronous, PM or Sychron reluctance motor. This leads to the following advantages:

Variable speed drives can also convert energy from natural and renewable sources, such as solar, wind or tidal, to feed into the grid or make it available for local consumption. Frequency converters are used in hybrid technologies to combine conventional energy sources and stored energy for higher-level energy management.

Inverters are also known by many other names: Variable speed drives, three-phase drives, variable speed drives, inverters, power converters and power converters.

They are available in versions for control cabinets and rooms, for mounting directly in the plant or as decentralized solutions for mounting close to the motor or engine.

Danfoss offers one of the largest product portfolios for all application areas in the low and medium voltage range.
