摘要
对于二相混合式步进电动机,如果绕组电流是两相对称的正弦交流电流,电动机将运行平稳,且具有较高的性能。在位置开环情况下,这种驱动方式实际上是一种细分驱动。文章给出了基于DSP的二相混合式步进电机SPWM驱动的软、硬件实现方法,并给出了实验结果,有实际意义和实用价值。
To the two-phase hybrid stepping motor, if the winding current is two-phase symmetrical AC current,the motor will have better performance and run smoothly. Under the condition of open loop with position,this driving mode is a mini-step drive in fact. This paper realizes the SPWM drive of two-phase hybrid stepping motor both in hardware and software based on DSP. Besides, the stator-winding current experimental curves are given out,result has practical significance and practicability.
