ABSTRACT:
An electric motor has a rotor for rotation in a stator and a plurality of permanent magnets arranged on an outer peripheral surface of the rotor. A radially inner side surface of each permanent magnet is a curved to generally be convex in a radially inward direction. The outer peripheral surface of the rotor has curved recess surfaces, each of which contacts the radially inner side curved surface of a corresponding permanent magnet so that magnetic flux between adjacent permanent magnets is considerably prevented from locally concentrating within the rotor.
