Claim:
1. A rotary electric machine, comprising: a rotor core; a plurality of permanent magnets embedded in the rotor core; and a stator core arranged so as to oppose the rotor core, wherein the plurality of permanent magnets include a pair of first permanent magnets, the pair of first permanent magnets being arranged so that first magnetic poles thereof having the same polarity oppose each other and are separated from each other on both sides of a magnetic path of d-axis by a predetermined distance, north poles of the first magnetic poles being disposed closer to the magnetic path of the d-axis than south poles of the pair of first permanent magnets, and wherein the rotor core includes gaps formed within the magnetic path of the d-axis, the gaps being disposed at positions to prevent the north poles of the first magnetic poles short-circuiting through a central portion of the rotor core.
