Motor control method

摘要

A motor control method comprises: inputting a PWM signal into a control unit for the control unit to obtain a direction command and a speed command by an identification rule, and generating a control signal according to the direction and speed commands by the control unit; and generating a driving signal according to the control signal by the driving unit for driving a motor to operate according to the direction and speed commands.

1. A motor control method, comprising:
inputting a PWM signal into a control unit for the control unit to obtain a direction command and a speed command by an identification rule, and generating a control signal according to the obtained direction and speed commands by the control unit, wherein the control unit obtains the direction command from a characteristic value of the PWM signal, and wherein a range of the characteristic value of the PWM signal is divided into a plurality of direction regions respectively mapping to a plurality of rotational directions of the motor; and inputting the control signal into the driving unit for the driving unit to generate a driving signal according to the control signal and to drive a motor by the driving signal corresponding to the direction and speed commands.
