摘要
PROBLEM TO BE SOLVED: To provide a concentrated winding permanent magnet synchronous motor capable of reducing cogging torque while keeping an induction voltage.;SOLUTION: A stator 14 includes: large teeth 24 around which a coil 28 is wound; and small teeth 26 which are narrower than the large teeth 24 and around which the coil 28 is not wound. A stator magnetic pole pitch θ is set at an angle where a torque component of the large teeth is switched from a plus side to a minus side in any degree component among a plurality of degree components included in the cogging torque of the large teeth 24 and the small teeth 26.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
