Abstract:
A rotor for a rotary electric machine includes: a rotor core which includes a magnet insertion hole; and a permanent magnet housed in the magnet insertion hole. The permanent magnet has an arc shape which is convex toward an axial line. The rotor core includes: an outer-circumference core part; an inner-circumference core part; and connection ribs which connect the outer-circumference core part and the inner-circumference core part. The permanent magnet is supported in the rotor core in such a manner that circumferential ends abut on an inner surface of the magnet insertion hole. A circumferential center portion of the permanent magnet is separated from an outer-circumference-side inner surface of the magnet insertion hole. In the circumferential center portion of the permanent magnet, a gap is provided between an outer-circumference-side outer surface of the permanent magnet and the outer-circumference-side inner surface of the magnet insertion hole.
