摘要
介绍了一种基于ST7MC专用电机控制芯片的电动车无刷直流电机控制系统,详细介绍了控制器的硬件、软件设计方案,分析并对比了有、无传感器的电机控制技术.实验证明,系统控制效果良好,硬件设计具有高性价比.
This paper gives a brief introduction to a control system for brushless direct current motor （BLDCM） based on the dedicated motor control chip ST7MC. The design scheme for hardware and software of the controller was presented in detail. The control technologies with or without sensors were analysed and compared. The experimental results show that this control system works well with high price-performance ratio.
