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.
