Abstract:
A motor, a driving circuit thereof and a driving method thereof are provided. The motor driving method includes: during a motor starting stage, when a detected rotor magnetic field is a first polarity and a polarity of an AC power source is positive, or the detected rotor magnetic field is a second polarity and the polarity of the AC power source is negative after a zero voltage crossing point of the AC power source, instantly sending a trigger pulse to a controllable bidirectional AC switch connected in series with a motor winding at both ends of the AC power source; during a motor operating stage, after the zero voltage crossing point of the AC power source, sending a trigger pulse to the controllable bidirectional AC switch after a delay time after the zero voltage crossing point. This method can provide a large torque during the motor starting stage.

Claim (Index 6):
A driving circuit for a motor comprising a stator and a permanent magnet rotor, the stator comprising a stator core and a stator winding wound on the stator core, wherein the driving circuit comprises:\n a controllable bidirectional AC switch connected in series with the stator winding between two ends of an AC power source; and a processing unit, configured to instantly send a trigger pulse to the controllable bidirectional AC switch, when a detected rotor magnetic field is a first polarity and a polarity of the AC power source is positive, or the detected rotor magnetic field is a second polarity and the polarity of the AC power source is negative after a zero voltage crossing point of the AC power source, during a motor starting stage; and the processing unit configured to send a trigger pulse to the controllable bidirectional AC switch after a delay time after the zero voltage crossing point, when the detected rotor magnetic field is the first polarity and the polarity of the AC power source is positive, or the detected rotor magnetic field is the second polarity and the polarity of the AC power source is negative after the zero voltage crossing point of the AC power source, during a motor operating stage.
