摘要: An accommodating recess ( 21 A, B) has a magnet portion 19 for permanent 17 and cavity 20 B), which is located at the q-axis side of portion. The opens through rotor outer circumferential surface 162 ). A starting point (Pa 1, Pb 1 ) an forming 201 on surface. intersects either magnetic pole or imaginary extended plane 23 facing 191 B). includes portions annular line (E). between d-axis intersection (Qa, Qb) plan
