Driving motor for electric vehicle

The utility model discloses a driving motor for an electric vehicle, mainly solving the technical problem that the cooling water pump of the conventional driving motor for an electric vehicle wastes electrical energy. The technical scheme adopted by the utility model is that the driving motor comprises a stator, a rotor, a housing, a motor rotating shaft, a front end cover and a rear end cover; a spiral liquid pipe is arranged in the housing; a cavity with a liquid inlet and a liquid outlet formed thereon is arranged on the rear end cover, and the liquid outlet is connected to one end of the spiral liquid pipe; a turbine blade is arranged in the cavity; and the liquid inlet and the other end of the spiral liquid pipe are connected to two ends of a radiator respectively. When the motor is in operation, the turbine blade is driven to rotate, so as to drive the coolant in the spiral liquid pipe to circulate, and further achieve the cooling effect; and when the motor is in an idle state and cooling is not needed, a cooling cycle system is stopped to save energy.
