摘要:

针对步进电动机控制精度低的问题,设计了一款多细分高精度的步进电动机细分驱动系统。系统采用细分驱动方法,使步进电动机两相绕组电流以阶梯正弦波的形式周期变换,实现步进电动机的256细分驱动。在仿真基础上,构建了以STM32F103ZET6为主控制器、TC1005为驱动芯片的步进电动机细分驱动系统,开发了上位机通信界面。对整个驱动系统进行了实验室联机测试,结果表明,系统控制精度明显提高,达到了预期的设计效果和要求。

Abstract:

Aiming at the low precision of the stepper motor, a multi-subdivision and high-precision stepper motor drive system was designed. The subdivision drive method was adopted in the system, so that the two-phase winding current of the stepper motor was changed periodically in the form of stepped sine wave, and the 256 subdivision drive of the stepper motor was already realized. Based on simulation, the stepper motor subdivision drive system was constructed, by using STM32F103ZET6 as the main controller and TC1005 as stepper motor drive chip. At the same time, the system software of the PC was designed. The whole drive system was connected by stepper motor test in laboratory, the results showed that the system control accuracy was improved obviously, and the desired design effect and requirement were achieved.
