An electric motor, a power system, a control method, and an electric vehicle. The electric motor comprises a first N-phase winding set and a second N-phase winding set, wherein the first N-phase winding set and the second N-phase winding set are both used for being connected to a traction battery by means of a conversion module. When the traction battery starts to be heated, the first N-phase winding set and the second N-phase winding set are powered on. The direction of a magnetic field generated by the first winding set and the direction of a magnetic field generated by the second winding set 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.
