The invention relates to the technical field of motors, and provides a motor with stator liquid outlet cooling windings, a power assembly and an electric vehicle. The motor of the stator liquid outlet cooling winding comprises an axial gap, two end plates and a plurality of punching sheets. The plurality of punching sheets are arranged between the two end plates along the axial direction of the motor, one end plate comprises a plurality of liquid outlets, the plurality of liquid outlets are arranged at intervals along the circumferential direction of the motor, and the axial gap is used for communicating at least two adjacent liquid outlets; the axial gap comprises an axial gap between two punching sheets, and at least one of the other punching sheets is arranged between the two punching sheets along the axial direction of the motor; or, the axial gap between one punching sheet and the end plate is arranged along the axial direction of the motor, and the end plate and one punching sheet are arranged adjacently. The cooling working medium can flow in the circumferential direction of the motor after entering the motor, and the heat dissipation effect of the motor is optimized.
