摘要
探讨了无位置传感器无刷直流电机的工作原理,分析了无位置传感器无刷直流电机预定位起动方法,并针对反电动势法进行了深入分析。对基于SH79F1611无刷电机的无传感器控制系统硬件电路和软件方案进行了设计。实验结果验证了该方案的可行性。
The working principle of sensorless brushless DC motors was briefly analyzed.The method of pre-setting starting was analyzed.Carried on the thorough analysis in view of method of back EMF,the scheme of hardware circuit and software scheme based on SH79F1611 was designed.The experimental result proves that the scheme is feasible.
