摘　　要：介绍一种基于TMS320LF2407 DSP的电励磁双凸极电机起动系统设计,针对传统的基于CAP中断捕获霍尔位置信号上升沿,从而确定换相时刻的提前角控制方式的不足,提出通过查询方式捕获霍尔信号上升沿,以此确定换相时刻,并通过实验验证了该控制方式的正确性。This paper describes a doubly salient electro-magnetic motor control systembased on DSP TMS320LF2407, the traditional advanced angle control mode is base on CAP interruption in order to capture the rising edge of hall, which is the basement of control during high speed. But this method has defect when the position signal is interfered. In order to deal with it, propose that the advance angle control can be realized by inquiry mode to capture the rising edge of the hall so that can determine the commutation time. Finally test and verify the effectiveness of the inquiry mode by experiment.
