Patent ID: 7417348

Claim:
A rotating electric machine, comprising: a stator provided with a plurality of windings; a rotor core rotatably fixed on a rotary shaft inside said stator; and a plurality of magnets disposed in slots formed in said rotor core, wherein said plurality of magnets are arranged such that, among those ones of said plurality of magnets constituting one magnetic pole, the magnet arranged on the magnetic pole end side is oriented to incline toward a magnetic pole center position and, a circumferential angle occupied by those ones of said plurality of magnets constituting one magnetic pole is in the range of 150 to 165 degrees in terms of an electrical angle wherein, among those ones of said plurality of magnets constituting one magnetic pole, the magnet arranged on the magnetic pole end side is oriented to inclined toward the magnetic pole center position such that an angle formed between said magnet and a line tangential to a point at which a straight line, which passes both the center of said rotary shaft and the center of said magnet crosses an outer circumferential surface of said rotor core is in the range of 2 to 6 degrees.
