Title:
STATOR AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/071029
Kind Code:
A1
Abstract:
One aspect of a stator of the present invention comprises phase coil parts of a plurality of phases star-connected to each other. The phase coil parts have a plurality of conductor connectors formed by connecting a plurality of conductors in series. The conductor connectors are arranged in a circle by being alternately passed through an Mth layer and an M+1th layer of slots. The conductor connectors have a first terminal part, a first section wave-wound from the first terminal part to one side in the circumferential direction, a folded-back part that connects to an end of the first section on one side in the circumferential direction, a second section which is wave-wound from the folded-back part to the other side in the circumferential direction, and a second terminal part that connects to an end of the second section on the other side in the circumferential direction. The first sections of the plurality of conductor connectors of the same phase are disposed in order in slots that are arranged next to each other one-by-one to one side in the circumferential direction. The second sections of the plurality of conductor connectors of the same phase are disposed in order in slots that are arranged next to each other one-by-one to the other side in the circumferential direction. The first terminal part and the second terminal part extend out from the outermost layer.
