Magnet embedded type motor and method for manufacturing the same

Abstract

A magnet embedded type motor capable of reducing a counter electromotive voltage while improving a torque is provided. The magnet embedded type motor of the present disclosure includes a stator and a rotor rotatably disposed inside the stator. The stator includes a stator core and a coil wound around the stator core. The rotor includes a rotor core and a plurality of magnet groups embedded in the rotor core along a circumferential direction. The plurality of magnet groups form a plurality of respective magnetic poles. A magnetic material constituting the rotor core has a saturation magnetic flux density higher than a saturation magnetic flux density of a magnetic material constituting the stator core by 0.2 T or more.
