摘要： A system and a method for controlling a sensorless motor are disclosed, where the system includes a motor driver and a zero crossing detector. The motor driver can drive the sensorless motor. The zero crossing detector can detect a zero-crossing point when the voltage of one motor coil of the sensorless motor is in a blanking period.

摘要： An apparatus and a method for driving a sensorless motor are described and shown in the specification and drawings, where the method includes steps as follows. First, a control signal is acquired, where the control signal has information of a predetermined rotational speed. Next, energy is supplied and progressively increased to the sensorless motor, so as to rotate a rotor of the sensorless motor. Then, a position of the rotor is detected. Finally, the energy is gradually regulated so that the sensorless motor is maintained at the predetermined rotational speed.
