Document Type and Number:
WIPO Patent Application WO/2023/171372
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a three-phase motor having: a first serial connection part (52A) in which two or more winding parts (45) are connected in series; and a second serial connection part (52B) in which two or more winding parts (45) are connected in series, wherein the first serial connection part (52A) and the second serial connection part (52B) are connected in parallel. This manufacturing method involves continuously drawing and winding a wire (46), thereby forming the entirety of a plurality of winding parts (45) for one phase, wherein in the step of forming the winding parts (45), winding the wire in one circumferential direction when the winding parts (45) are viewed from an inner peripheral side of a yoke part along the radial direction of the yoke part, thereby forming the winding parts (45) included in one serial connection part in the first serial connection part (52A) and the second serial connection part (52B), and winding the wire (46) in the other circumferential direction, thereby forming the winding parts (45) included in the other serial connection part.
