Abstract:
A rotating element with embedded permanent magnets is provided that includes: a rotor core adapted to be within the diameter direction of a stator; first permanent magnets embedded near the exterior circumference face of the core, and orthogonally extending with a d axis; and second permanent magnets embedded on both sides of each of the first magnets, and extending along a q axis. The rotating element further includes gaps formed in the core away from both circumference direction ends of the first magnets. The gaps further include exterior end parts at the furthermost exterior side with respect to the diameter direction of the core, and interior end parts at the furthermost interior side with respect to same. The magnetic pole faces of the first magnets are located between the exterior and interior end parts of the gaps.
