:A device through the control DC motor terminal voltage to control DC motor speed is de- signed. And the UPS power supply, PWM drive circuit, microcontroller PWM wave theory and the power circuit, PWM drive circuit are introduced. Gives the circuit diagram, power drive circuit and the micro- controller circuit generating PWM waveform procedures. Finish after the debugging, testing, power sup- ply, drive circuit, PWM waveform to achieve the expected target, and the success of the speed regulation experiment.
