Claim Text:
1. An electric excitation method for an electric excitation permanent magnet switched reluctance motor having a rotor, position sensors, an excitation control power source and a stator having even number of stator switch components, the method comprising: supplying power by the excitation control power source to M phase lines on the stator in sequence and cyclically; stopping power supplying by the excitation control power source to phase (M−1) in a time period TM only when Δt only when Δt sending position signals of stator and the rotor by the position sensors to the excitation control power source; controlling, by the excitation control power source, start and end moment of supply power to each phase line of the stator; and controlling running status of the motor.
