Rotating electric machine

摘要

A rotating electric machine includes a stator and a rotor. The rotor includes a plurality of permanent magnets and a rotor core. The plurality of permanent magnets are to form magnetic poles. The rotor core includes stacked steel sheets, magnet holes, a plurality of cutouts, and fixing elements. The magnet holes are provided in the stacked steel sheets. The plurality of permanent magnets are provided in the magnet holes. The plurality of cutouts are provided between the plurality of permanent magnets located adjacent in a circumferential direction of the rotor core to form different magnetic poles. The fixing elements are to fix the steel sheets to each other. The fixing elements are provided at positions on an outer peripheral side of inner peripheral end portions of the cutouts and between the cutouts and the magnet holes.
