An electric motor, a power system, a control method, and an electric vehicle. The electric motor (30) comprises a first N-phase winding set (201) and a second N-phase winding set (202), wherein the first N-phase winding set (201) and the second N-phase winding set (202) are both used for being connected to a traction battery (100) by means of a conversion module (300). When the traction battery (100) starts to be heated, the first N-phase winding set (201) and the second N-phase winding set (202) are powered on. The direction of a magnetic field generated by the first winding set (201) and the direction of a magnetic field generated by the second winding set (202) have a phase difference, such that the magnetic fields counteract each other; and a magnetic field intensity in a stator winding of each phase is reduced, and an air-gap magnetic flux is also reduced, thereby alleviating the problems of electric motor heating and electric motor NVH.
