Title:
STATOR, ROTARY ELECTRIC MACHINE, AND ELECTRIC ACCESSORY DEVICE FOR AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2017/130701
Kind Code:
A1
Abstract:
Provided are a low-vibration stator, a rotary electric machine, and an electric accessory device for an automobile, which have reduced electromagnetic excitation force. The stator 20 is equipped with: 18n (n being an integer of 1 or more) teeth 22 arranged opposing a rotor having 14n or 22n magnetic poles; and stator coils 25 wound around the teeth in a concentrated-winding method. The stator coils include an independent-phase coil group 251 wherein the stator coils wound around adjacent teeth have different phases, and a continuous-phase coil group 252 wherein the stator coils wound around adjacent teeth have the same phase, and the maximum amount of magnetic flux inside the teeth around which the independent-phase coils are wound is greater than the maximum amount of magnetic flux inside the teeth around which the continuous-phase coils are wound.
