摘要
主要介绍对于基于DSP技术的无位置传感器的无刷直流电动机控制系统设计 ,重点介绍了如何采用单电阻检测相电流和转子位置估算的问题 ,同时 。
The design of sensorless control of 3_phase brushless DC motor by TMS320C2xx was summarized. Especially, the process of how to measure phase current by using a single line resisitor and calculate the back electromotive force was introduced. In addition, the solution of starting BLDC is also given.
