Title:
PERMANENT MAGNET ROTATING MACHINE
Document Type and Number:
Japanese Patent JP3913205
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a permanent magnet rotating machine that can satisfactorily improve efficiency.
SOLUTION: A magnet housing hole 31a for housing permanent magnets 41a, 42a is formed in a main pole (a) of a rotor 20. An external periphery of the rotor 20 is formed such that a first external peripheral part 22a and second peripheral parts 23a, 23d are alternately connected to the external periphery of the rotor. The first external peripheral part 22a intersects with a line (d-axis) that connects the center O of the rotor 20 and the circumferential center of the main pole (a), and is formed into an arc shape having a radius R with the center O of the rotor 20 as a center. The second external peripheral parts 23a, 23d intersect with a line (q-axis) that connects the center O of the rotor 20 and the circumferential center of an auxiliary pole arranged between the main poles, and are formed into arc shapes each having a radius Rq with a position Q that is shifted by a prescribed distance in a direction opposite to the side at which the auxiliary pole on the q-axis is arranged, as a center. The rotor windings are housed in slots 16a to 16x in a manner of a distribution winding system.
