摘要

A permanent magnet rotating electric machine includes a stator having a plurality of teeth formed in a stator core, concentrated wound armature windings wound around the plurality of teeth, and a rotor having a plurality of holes formed in a rotor core for accommodating permanent magnets. Permanent magnets are inserted into the plurality of holes of the rotor. The permanent magnets are each formed or arranged as a convex "V" and "U" with respect to the shaft of the rotor.
