Abstract

　回転子側のばらつきに起因するコギングトルク成分を低減することができる永久磁石型回転電機を得る。多角形の回転子コア及び複数の永久磁石を有する回転子と、固定子コア及び電機子巻線を有する固定子とを設けた永久磁石型回転電機において、極数をＭ、スロット数をＮとし、Ｍ個の永久磁石を周方向に順番に１番目からＭ番目までとし、ｉ番目（ｉ＝１，２，…，Ｍ）の永久磁石における、回転軸の中心から径方向で等距離かつ周方向で等間隔である基準位置からの周方向の位置ずれ量をｈiとしたとき、２πＮ（ｉ－１）／Ｍ（ｒａｄ）の角度方向の合計Ｍ個の単位ベクトルを定義し、それぞれの単位ベクトルに、位置ずれ量ｈiを乗じた合計Ｍ個のベクトルの総和のベクトルの大きさが、位置ずれ量ｈiの絶対値の最大値よりも小さい。
