Title:
STATOR ASSEMBLY, ELECTRIC MOTOR, POWERTRAIN AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/155510
Kind Code:
A1
Abstract:
Provided in the present invention are a stator assembly, an electric motor, a powertrain and a vehicle. The stator assembly comprises a stator core and a stator winding. The stator core is provided with a plurality of stator slots, which are distributed in the circumferential direction of the stator core. A winding portion of one winding wire of each phase of the stator winding is disposed in the stator slots. Leading-out terminals of the winding wire of each phase are all located on a radial inner side of the winding portion based on the stator core, and are evenly distributed in the circumferential direction of the stator core. The leading-out terminals are disposed on the radial inner side of the winding portion and are evenly distributed in the circumferential direction, such that star-point terminals can be disposed on an outer side or an inner side, a star connection method or a delta connection method can be used as required, the resistances of all phases can be balanced, and the currents in all the phases can also be balanced, thereby improving the operational stability and related performance of the electric motor.
