摘要: A rotor of an embedded magnet type motor is disclosed. A rotor core of the motor includes first accommodation holes and V-shaped accommodation holes The first accommodation holes extend in radial directions, and the V-shaped accommodation holes protrude radially outward. The rotor core has grooves at positions corresponding to the first accommodation holes on the outer periphery of the rotor core. Each groove has a width as a dimension in the circumferential direction when viewed from the axial direction. Each first magnet has a width as a dimension in the circumferential direction when viewed from the axial direction. The width of the grooves is larger than the width of the first magnets.
