Abstract:
A control module adapted to brush and brushless motors essentially applies a magnetic sensor to generate detecting signals in response to the status of the motor and deliver those signals to a control unit. The control unit further converts the signals into discrete diverting signals for driving the rotating direction, phase commands for controlling the motor phase, and a pulse width modulation (PWM) for adjusting the motor speed. A phase refining circuit thence receives those transformed signals and confirms merely a selected phase command attendant with the diverting and PWM signals for assisting a stable operation of the motor. Therefore, such control module not only applies to different types of motors but uses the separate transmissions of the signals responsible for designated instructions to attain facile controls and appropriate adjustments to the errors of the motor phase or motor velocity and efficiently decrease the occurrence of breaking the motor.
