Description
本発明に係る永久磁石式同期モータは、ステータ突起と、円環状に形成され、ステータ突起に付けられた巻線と、永久磁石とを有する永久磁石式同期モータにおいて、永久磁石に関するばらつきによって発生するコギングトルクを、ステータ突起間における巻線のコイルエンド部に突起を設けることで、コギングトルクの逆相成分を作り出して打ち消すものである。 A permanent magnet type synchronous motor according to the present invention is caused by variations in a permanent magnet in a permanent magnet type synchronous motor having a stator protrusion, an annularly formed winding attached to the stator protrusion, and a permanent magnet. The cogging torque is canceled by providing a projection at the coil end portion of the winding between the stator projections , thereby creating a reverse phase component of the cogging torque .
