Japanese Patent JP6672894
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress cost increase, suppress unbalance of a magnetic field and excess currents to a brush, and also reduce resonance.SOLUTION: In a rotary electric machine M, each of a plurality of coil parts 26 strides across three teeth 22. In each of a plurality of windings 16 forming the plurality of coil parts 26 are formed three coil parts 26 serially arranged at equal intervals in a circumferential direction of an armature core 12, of the plurality of coil parts 26. Each winding 16 having the three coil parts 26 is connected to one segment 24 of a plurality of segments 24 and the other segment 24 having the same phase as the one segment 24. Around the plurality of teeth 22 are wound the coil parts 26 in plural layers respectively, where at least the coil part 26 in the first layer of the coil parts 26 in a plural layers is different in the number of turns from the coil parts 26 in the other layers.SELECTED DRAWING: Figure 1
