The utility model discloses a motor stator assembly, a motor and an electric vehicle having the motor. The motor stator assembly comprises a stator iron core and at least two sets of symmetrical three-phase windings, which are arranged to wind the stator iron core respectively, wherein phase differences among three phases Ui, Vi and Wi of each set of the three-phase windings are a 120&#xb0; electrical angle, and i is the set number of the three-phase windings. In order to address the problem of high output power of drive system, the motor stator assembly uses two sets of three-phase windings having a symmetrical spatial arrangement, and each set of windings is considered as an independent unit and is controlled via a power device respectively; finally, the output powers are superimposed so that the capacity of the inverter is increased while also avoiding problems of equalized current and over-voltage.
