PERMANENT MAGNET EMBEDDED ROTATING ELECTRIC MACHINE, CAR AIR CONDITIONER MOTER, AND ENCLOSED ELECTRIC COMPRESSOR

摘要

Each of the plurality of portions of the outer circumference of the corresponding rotor in the center magnetic pole of the plurality of permanent magnets, the plurality of circumferential portion is formed. Each circumferential portion, forms part of a virtual circumferential surface of the rotational center axis of the rotor and concentric. A plurality of circumferential portions, and are spaced apart from each other in the circumferential direction. Each of a set of convex shape, the pieces of each adjacent pair of circumferential portions. Each of the convex-shaped portion, with a box located at the inside with respect to the radial direction of the imaginary circumferential surface is convex toward radially outward. Each convex portion toward a radially outward portion has a plurality of convex edges. Thus, with the inhibited deterioration of the average value of the output torque, reluctance rotating electrical configuration of the reluctance torque is not used to increase the average value of the output torque device is provided.
