| Abstract: | This paper presents the basic principle of sensorless brushless DC motor commutated by using the zero-crossing method of back EMF, and designs the detection circuit. Analyze the rotor seat phase shifting which the filter brings to the electric circuit , proposes the phase revises method, carries on the confirmation through the experiment. |
