    Abstract: A motor and a powertrain. The motor includes a stator, an end cover, and a housing. The housing may be configured to install the stator and the end cover, and the stator and the end cover are adjacently arranged along an axial direction of the motor. The end cover includes an outer circumferential surface, a side surface, and an internal channel. The outer circumferential surface includes at least one liquid inlet, and at least one liquid inlet is configured to receive coolant through the housing. The side surface faces the stator, and the side surface includes a plurality of liquid outlets. In the motor, the coolant can enter the end cover through at least one liquid inlet and be sprayed to the stator through the plurality of liquid outlets, to cool the stator.

    Abstract: A stator includes a stator core and a stator winding. An inner wall of the stator core is provided with M winding slots, the M winding slots are uniformly disposed in a circumferential direction of the inner wall of the stator core. The stator winding includes flat wire conductors inserted in the winding slots, N layers of flat wire conductors are disposed in any one of the winding slots, and phase units of a first-phase winding, phase units of a second-phase winding, and phase units of a third-phase winding are sequentially and periodically arranged along the inner wall of the stator core. Each phase winding includes P parallel branches. Any one of the parallel branches connects flat wire conductors of M·N/3P layers.
