Title:
回転電機及び交流発電機
Document Type and Number:
Japanese Patent JP4389918
Kind Code:
B2
Abstract:
The invention relates to a rotating electric machine wherein it is made easy for a stator winding to be wound around a stator core and degradation in efficiency is prevented as much as possible. A stator 6 includes a plurality of phases, i.e., of circumferentially divided stator magnetic poles 6a, 6b, 6c. The stator magnetic poles 6a, 6b, 6c are each composed of an arcuate stator core 13 having a plurality of axially extending claw poles 16b and a circumferentially elliptically wound stator winding 14. The stator magnetic poles 6a, 6b, 6c are magnetically divided; therefore, magnetic flux leakage is reduced to improve efficiency. Air flowing between the stator magnetic poles 6a, 6b, 6c can improve a cooling effect.
