Abstract

A motor control system includes an electric motor and inverter. The electric motor includes a stator, a rotor, and a winding structure. The stator includes an iron core with a plurality of slots formed therein along a radial direction of the stator. The winding structure has a plurality of hairpin wires with pins disposed in the slots. The winding structure is configured to provide a plurality of phase windings and each phase winding includes a plurality of motor windings. The inverter includes a switching controller configured to control the turning-on and turning-off of the motor windings of each phase winding of the winding structure. When the electric motor operates in a high-speed mode, the switching controller controls the turning-on and turning-off of the motor windings of each phase winding such that a number of the phase windings turned-on is 1/3 less than a number of all the phase windings.
