摘要：
A permanent magnet rotating machine has a stator, in which armature windings are formed in a plurality of slots formed in a stator iron core, and also has a rotor, in which two magnet insertion slots are formed for each pole in a rotor iron core in a V shape when viewed from the outer circumference of the rotor and one permanent magnet is embedded in each magnet insertion slot with polarity alternating for each pole; a wall at one end of the magnet insertion slot on the external diameter side of the rotor is formed with three arcs having different curvatures, one of the three arcs being parallel to the outer circumference of the rotor, and a wall at the other end of the magnet insertion slot on the internal diameter side of the rotor is formed in an arc shape.
