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 9):
The driving circuit according to  claim 6 , wherein the controllable bidirectional AC switch is a TRIAC, a first anode of the TRIAC is grounded or receives a low direct current voltage, the first anode of the TRIAC is also connected to a first end of the AC power source, a second anode of the TRIAC is connected to a second end of the AC power source via the stator winding and a fuse, and a control electrode of the TRIAC is connected to the processing unit via a resistor.
