Provided are an electric drive system for a motor vehicle and a motor vehicle using the electric drive system. The electric drive system for a motor vehicle comprises: an inverter unit () configured to convert externally-supplied DC power to AC power; an electric motor unit () configured to convert the power from the inverter unit () into mechanical rotation and output the mechanical rotation from an output shaft (); and a gearbox unit () configured to decelerate the rotation transmitted from an input shaft () and output the decelerated rotation. The electric motor unit (), the gearbox unit () and the inverter unit () have respective independent enclosures. The electric motor unit (), the gearbox unit () and the inverter unit () are detachably and mutually connected in an axial direction along the input shaft () of the gearbox unit () with the gearbox unit () positioned in between. The enclosure of the inverter unit () has the minimum thickness in the axial direction.

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.
