Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/065462
Kind Code:
A1
Abstract:
Provided is a technique which enables a decrease in the size of a multiple-phase, claw pole-type rotary electric machine. A claw pole motor 1 according to an embodiment of the present disclosure is provided with a stator 20 in which six claw pole-type stator units 21 are stacked in an axial direction. Two stator units 21 included in the six stator units 21 that are adjacent to each other in the same axial direction and having the same phase have respective claw magnetic poles 211B disposed in a substantially mirror image relationship, with respective windings 212 wound in opposite directions when viewed from circuit ends on a power supply side and a neutral point side. In addition, the two stator units 21 included in the six stator units 21 that are adjacent to each other in the axial direction and having the same phase have a same magnetic pole polarity due to an armature current through the claw magnetic poles 211B disposed at the ends in the axial direction of the stator cores 211 facing each other in a substantially mirror image relationship.
