Title The design of the driving circuit of stepper motor speed control system
Abstract Stepper motor is widely used in the industrial field. The research on the driving circuit is also in progress.However,in the process of development,
multiplier effect would be achieved, if the simulation is conducted before making a mock-up. Therefore, there is certain practical significance using the Proteus software to simulate the driving circuit.
In this paper, the driving circuit of stepper motor is first designed. Also, Three-phase six pat stepper motor is chosen. The power amplification unit is the driving circuit with single voltage. MCU is the pulse generating and distributing unit. After the driving circuit is designed, with the Proteus software, the simulation of stepper motor is conducted. The simulation results show that, the stepper motor can work normally, start or stop working, operate clockwise or anticlockwise, and accelerate or decelerate.
