Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2019047630
Kind Code:
A
Abstract:
To provide a rotary electric machine which can reduce cogging torque.SOLUTION: Each tooth facing part 14 has a high magnetic resistance part, each tooth includes: a first tooth 10a in which high magnetic resistance parts 11, 11A are arranged on one side of a circumferential direction from the center of the circumferential direction of a tooth base part 13; and a second tooth 10b in which the high magnetic resistance parts 11, 11A are arranged on the other side of the circumferential direction from the center of the circumferential direction of the tooth base part 13. In each of the high magnetic resistance parts 11, 11A, the center in the circumferential direction of the high magnetic resistance parts 11, 11A is arranged closer to a side of the tooth base part 13 than a linear line connecting a rotation center of a rotor 3 and ends 24a and 24b on a circumferential direction side at a boundary part 24 between the tooth facing part 14 and the tooth base part 13.SELECTED DRAWING: Figure 3
