A motive power system for an electric vehicle includes a permanent magnet synchronous motor and an electrically excited synchronous motor, one of which being a front drive electric machine for driving front wheels of the electric vehicle, and the other of which being a rear drive electric machine for driving rear wheels of the electric vehicle. A peak power and a peak torque of the permanent magnet synchronous motor are less than a peak power and a peak torque of the electrically excited synchronous motor. The powers outputted by the permanent magnet synchronous motor and the electrically excited synchronous motor are dynamically adjusted according to real-time operating conditions of the electric vehicle, such that a power loss sustained by the motive power system reaches a predetermined minimum value.
