摘要:
An object is to provide a rotary electric machine capable of suppressing degradation of strength in high-speed rotation and reducing a torque ripple.A rotor of a rotary electric machine according to the present invention includes a rotor core provided with a magnet insertion hole that forms a space into which a permanent magnet is inserted and a non-magnetic portion facing the space to form a part of the magnet insertion hole, wherein the non-magnetic portion is provided asymmetrically with respect to a d-axis.
