摘要
无刷直流电机体积小、重量轻、效率高、出力大、特性好,有着越来越广泛的应用。但由于BLDCM其换相转矩脉动较大,起动磁阻转矩大,在伺服控制应用上有所限制。本文对其四象限运行的控制问题进行了综述,首先研究了其四象限运行拓扑,然后对其在该领域应用的关键问题进行了分析。
Brushless DC motor has some advantages： small size, light weight, high efficiency, large output, good performance. It has become more and more widely used. However, due to the large torque ripple of BLDCM, the starting reluctance torque is large, and it is limited in the application of servo control. In this paper, the control problem of four quadrant operation was reviewed, the four quadrant running topology was studied, then carried on the analysis to the key problem of the application.
