Patent number: 11658536Abstract: A rotary electric machine includes a multi-phase winding including magnetic poles circumferentially arranged in a circumferential direction. The multi-phase winding includes crossover wires each connecting two same-phase single coils that provide same-phase magnetic poles of the magnetic poles. The crossover wire includes an inter-pole crossover wire and an end crossover wire. The inter-pole crossover wire extends between one end and another end of the multi-phase winding in an axial direction of the multi-phase winding. The inter-pole crossover wire extends through an inter-pole gap between two adjacent poles of the magnetic poles. The end crossover wire extends in the circumferential direction on the other end of the multi-phase winding.Type: GrantFiled: June 4, 2020Date of Patent: May 23, 2023Assignee: DENSO CORPORATIONInventors: Masayuki Echizen, Seigo Shinoda

Publication number: 20230089778Abstract: A rotary electric machine includes a multi-phase winding including magnetic poles circumferentially arranged in a circumferential direction. The multi-phase winding includes crossover wires. Each crossover wire connects two single coils functioning as two of the magnetic poles that are same in phase. The crossover wire includes an inter-pole crossover wire and an end crossover wire. The inter-pole crossover wire extends between one end and another end of the multi-phase winding in an axial direction of the multi-phase winding. The inter-pole crossover wire extends through an inter-pole gap between adjacent two of the magnetic poles. The end crossover wire extends in the circumferential direction on the other end of the multi-phase winding.Type: ApplicationFiled: December 2, 2022Publication date: March 23, 2023Applicant: DENSO CORPORATIONInventors: Masayuki ECHIZEN, Seigo SHINODA

Publication number: 20220123608Abstract: A motor includes a stator that includes a stator core and coils. The stator core is formed of a magnetic material and has a plurality of teeth arranged at intervals in a circumferential direction. The coils are formed of electrically-conductive windings wound around the teeth. Moreover, the motor also includes a rotor having a plurality of magnets arranged in radial opposition to the stator core and at intervals in the circumferential direction. The rotor is configured to rotate upon supply of electric current to the coils. Furthermore, the motor also includes a plurality of pseudo-teeth formed of a magnetic material and each located in a circumferentially intermediate area between a circumferentially-adjacent pair of the teeth. The pseudo-teeth are arranged so as to be concentrated in a part of the stator core in the circumferential direction.Type: ApplicationFiled: December 27, 2021Publication date: April 21, 2022Applicant: DENSO CORPORATIONInventors: Masayuki ECHIZEN, Seigo SHINODA, Naoto NATSUME
