摘要： A motor control apparatus includes a phase sensing circuit, a current sensing circuit, a controller and a driving circuit. The driving circuit receives a first driving signal and then controls a phase switching state of the magnetic pole of the motor so as to drive the motor in accordance with the first driving signal. The phase sensing circuit detects the phase switching state of the magnetic pole to generate and output a phase switching signal to the controller during the motor is operating. The current sensing circuit detects a current flowing through the motor to generate and output a current phase signal to the controller. The controller compares a phase difference between the phase switching signal and the current phase signal to generate and output a second driving signal to the driving circuit. The driving circuit controls the phase switching state of the magnetic pole for driving the motor in accordance with the second driving signal.

摘要： A motor control apparatus includes a phase sensing circuit, a current sensing circuit, a phase lock loop, a controller and a driving circuit. The phase sensing circuit detects a phase switching state of a magnetic pole of a motor circuit, and then generates and outputs a phase switching signal to the phase lock loop when the motor is operating. The current sensing circuit detects a current flowing through a coil of the motor to generate and output a current phase signal to the phase lock loop. The phase lock loop compares a phase difference between the phase switching signal and the current phase signal to generate and output a phase-switch controlling signal to the controller. The controller generates and outputs a driving signal to the driving circuit in accordance with the phase-switch controlling signal. The driving circuit controls the phase switching state of the magnetic pole of the motor to drive the motor to rotate in accordance with the driving signal.
