Original Abstract Submitted
A rotor used for a motor includes a rotor core, and a plurality of permanent magnets embedded in a corresponding plurality of embedding holes in the rotor core configured to include flux barriers at both ends of the plurality of embedding holes in the rotor core and to include a plurality of magnetic poles. The rotor core includes a plurality of grooves on an outer peripheral surface, the plurality of grooves, with the two paired grooves, are away from an axis that becomes the q-axis when the motor is operated, and are arranged symmetrically about the axis, and the rotor core has such a cross-section that a first angle between two lines passing through the two grooves and the center of the rotor core is smaller than a second angle between the axis-side end face of the two flux barriers adjacent to each other across the axis.
