Thus the reduction of energy consumption is the main topic in many applications. Especially modern speed-controlled electric drives offer the chance to save maximum energy. A solution with remarkable energy efficiency is offered by using perma-nent magnet synchronous motors (PM motors ). They are operated exclusively with frequency inverters and are characterised by a significantly higher efficiency (>IE3) and an improved part load behaviour than asynchronous motors .
