Disclosed is a motor, a control method, a power system, and an electric vehicle. Each phase stator winding of the motor includes two sub-winding sets. When a traction battery needs to be heated, the two sub-winding sets of the motor store electrical energy and provide alternating currents to the traction battery through an inverter, so that the traction battery uses its internal resistance for heating. In addition, the two sub-winding sets generate opposite magnetic fields which cancel each other out, so that the strength of the magnetic field inside each phase stator winding and the air gap magnetic flux are reduced, thereby alleviating the heat generation and NVH problems of the motor.
