Publication number: 20240429770Abstract: A stator includes a stator core, an insulator, and a plurality of coils. The stator core is equipped with teeth which are arranged away from each other in a circumferential direction of the stator. The insulator is secured to the stator core. The coils are made of windings of conductive wires around the teeth. The stator also includes terminals (i.e., first terminals and a second terminal). The terminals include insulator retainers (i.e., first insulator retainers and a second insulator retainer) and crimps. The insulator retainers are secured to the insulator. Each of the crimps is disposed between two of the coils which are arranged adjacent to each other in the circumferential direction. Ends of the coils (i.e., first ends and second ends) are secured to the crimps.Type: ApplicationFiled: September 3, 2024Publication date: December 26, 2024Applicant: DENSO CORPORATIONInventors: Ryo MITANI, Naoto NATSUME, Masayuki ECHIZEN
