ROTATING ELECTRICAL MACHINE, AND ELECTRIC VEHICLE USING SAME

摘要

The purpose of the present invention is to provide a rotating electrical machine that has the ability to improve the efficiency of the high-speed operating state of the rotating electrical machine. The purpose of the present invention is also to use this rotating electrical machine to improve the efficiency of the high-speed operating state of an electrical vehicle. Provided are a rotor and a stator having a stator winding and a stator core provided with slots. The rotor comprises: a rotor core provided with laminated magnetic steel sheets, and upon which a plurality of poles positioned in a circumferential direction are formed; and a plurality of first permanent magnets and a plurality of second permanent magnets that form the plurality of poles. The plurality of first permanent magnets and the plurality of second permanent magnets that form the poles of the rotor are each provided with a different recoil permeability.
