Permanent magnet synchronous motors for inverter operation3 ContentsIndroduction 5 Technical explanations 6 Energy saving motors 19 High-power motors 21 Torque motors 23 Dimensions 26 Contents4 Certifi cation5 Innovative drives made in GermanyThe reduction of CO2-emission is the big challenge of our time. 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 . In addition PM- motors can reach a higher output than asyn-chronous motors of the same size. Because of the rotor fol-lowing exactly the rotating field, PM- motors can be used for example in conveyor belts with several drives that are operated synchronously.
