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 4):
The motor driving method according to  claim 1 , wherein during the motor operating stage, the method comprising:\n detecting at least one of the parameters including voltage value of the AC power source, frequency of the AC power source, temperature of the motor, temperature of environment surrounding the motor, and determining the delay time of sending the trigger pulse to the controllable bidirectional AC switch according to the detected parameter; detecting the zero voltage crossing point of the AC power source; when the zero voltage crossing point of the AC power source is detected, detecting the magnetic field of the rotor and the polarity of the AC power source; 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, sending the trigger pulse to the controllable bidirectional AC switch after the delay time after the zero voltage crossing point.
