Rotary electric machine and vehicle equipped with rotary electric machine

Abstract:

A rotary electric machine includes: an annular stator including coils disposed in a stator core; and an annular rotor disposed inside the stator and opposite to an inner circumferential wall of the stator. The rotor includes a rotor core having receiving holes for magnetic material members. The receiving holes extend in an axial direction of a drive shaft and are arranged in a circumferential direction of the rotor core. The rotor includes a pair of protrusions provided in each receiving hole. The protrusions jut out from an inner wall of the receiving hole to hold a magnetic material member. Each magnetic material member includes a hard magnetic material member and a soft magnetic material member stacked one on another in a direction of magnetization. The soft magnetic material member is disposed to border the inner wall of the receiving hole at positions where the protrusions are provided.
