Abstract
A system of driving and controlling a motor is provided. A main controller adjusts frequencies of all or some of pulse waves of an initial pulse width modulation signal to output a pulse width modulation signal according to instruction information. The adjusted frequency of each of the pulse waves is equal to a first preset frequency or a second preset frequency. When a motor driver drives the motor to stably rotate, the motor driver decodes each of the pulse waves having the first preset frequency into a first message and decodes each of the pulse waves having the second preset frequency into a second message. The motor driver arranges and combines all of the first messages and the second messages that are decoded from the pulse waves to obtain the instruction information. The motor driver executes an operation instructed by the instruction information.
