Title:
STATOR AND ROTARY ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/153975
Kind Code:
A1
Abstract:
This stator comprises: an annular stator core (21) that has, in the circumferential direction, a plurality of teeth (21b) extending radially inward; an insulator (22) that is made of an insulating resin material and that covers prescribed parts of the stator core; a winding wire (23) that is wound on the teeth of the stator core with the insulator therebetween; and terminals (24, 26) made of a conductive metal sheet material connected to terminal parts (23a) of the winding wire. The stator is configured to be connectable to an electrical connection target (14) via the terminals. The terminals have connection terminal parts (24a, 26a) that extend in an axial direction for connection to the connection target, winding connection parts (24c, 26c) for connection to the terminal parts of the winding wire, and extension parts (24b, 26b) that are provided between the connection terminal parts and the winding connection parts and that extend in the circumferential direction. Portions (24d, 26d, 24e, 26e, etc.) of the extension parts are supported so as to abut against support parts (22a) of the insulator at a plurality of places to maintain an attitude.
