| Abstract: | Deal with such problems as a long time, out-of-step and weak load ability of brushless DC motor （BLDCM） self-starting at present, an improved method is proposed based on the three-step starting technique. This paper ana- lyzes the conditions to prevent the motor from losing-step during the accelerating step and the state-changing step of the three-step starting. Experimental results are also presented to verify the analyses is available. |
