Title:
MOTOR STATOR ASSEMBLY, MOTOR, AND ELECTRIC VEHICLE HAVING MOTOR
Document Type and Number:
WIPO Patent Application WO/2018/209778
Kind Code:
A1
Abstract:
A motor stator assembly, a motor, and an electric vehicle having the motor. The motor stator assembly comprises: a stator core, and at least two sets of symmetric three-phase windings configured to separately wind the stator core. a 120° electrical angle is present between each two of three phases, i.e., Ui, Vi, and Wi, of each set of three-phase winding, and i is the number of sets of the three-phase winding. The motor stator assembly uses two sets of spatially symmetric three-phase windings, magnetic circuits of the two sets of three-phase windings are independent from each other, each set of windings is taken as an independent unit and is individually controlled by a power device, and output powers are finally superposed, such that the capacity of an inverter is improved, and the problems of current sharing and overvoltage are also avoided.
