Description

Synchronous motors (SM) with rare-earth magnets in the rotor have higher efficiency and less mass than induction motors (IM). However, SMs are costly for there are expensive rare-earth magnets in their rotors. Synchronous reluctance motor with ferrite magnets in the rotor (PMSynRM) is a good alternative to SM. The mass of PMSynRM is approximately equal to that of SM and lower than of IM. The manufacturing cost of PMSynRM is approximately equal to that of IM and much lower than of SM, because ferrite magnets are several times cheaper than rare-earth magnets. PMSynRM energy efficiency is higher than IE5 level. New design of energy-efficient PMSynRM is presented. The PMSynRM has shown highest efficiency in experiment among SM and induction motor. The PMSynRM can replace the IM or SM and can be applied in variable speed applications such as pumps, fans, compressors, extruders, conveyors, mixers, household appliances, servo drives and electric traction drives.
