永久磁石式回転電機
Document Type and Number:
Japanese Patent JP5663936
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a permanent magnet type revolving armature capable of reducing manufacturing costs while improving a reluctance torque.SOLUTION: The present invention relates to a permanent magnet type revolving armature 1 including a stator 2 around which a magnetic coil is wound, and a rotor 5 which is confronted to the stator 2 with a predetermined void 3 therebetween and is supported to be freely rotatable and in which a permanent magnet is embedded. In the rotor 5, a pair of slots 13a, 13b and a pair of slots 14a, 14b formed inside a rotor core throughout in an axial direction and arranged in a V shape which is opened from a rotation center axis side to an outer circumference side are formed in a double-layer structure in a radius direction. Permanent magnets 15a, 15b and permanent magnets 16a, 16b are inserted and held in each of the slots in such a way that magnetic poles being adjacent in a circumference direction become different polarities and that voids are formed at both ends in the relevant slot.
