摘　　要：介绍了一种基于MCP8025的无位置传感器无刷直流电机控制系统的设计。系统采用升频升压的方式实现电机起动后,利用MCP8025内部的检测模块较容易地实现了反电动势过零检测。从控制系统的硬件和软件设计方案及控制策略两个方面详细介绍了控制系统的实现方法,试验结果验证了该控制方案的可行性。A control system for sensorless brushless DC motor（ BLCDM） based on MCP8025 was presented. The system was developed with increasing frequency and increasing voltage synchronous starting method,and using the detection function of MCP8025 to make easier the realization of bemf zero crossingpoint detection. The hardware structure and software design of sensorless BLCDM control system was described in details. The result of experiment verified the feasibility of the control strategy.
