| Abstract: | Presented the design method for controlling stepping motor. Combined with MCU and FPGA and incremental encoder, a complete motion control platform was constructed. The system consisted of bus interface unit, loop control unit, PWM pulse width modulation unit and LMD18200 drive unit. The practice showed that the driving logic of LMD18200 could make the stepper motor run stably and efficiently. It could effectively reduce the noise during the operation of the motor and the vibration during start and stop. The method was better than most conventional stepper motor driving methods. |
