Abstract

The inductance method is presented for initial rotor position estimation of brushless dc motor (BLDC) in the sensorless control. This method is based on the salient effect and magnetic saturation effect of the interior permanent magnet BLDC. The method includes two processes: one estimates the rotor position of magnetic pole; the other determines the direction of the magnetization at the estimated position at the same period. The experiment result is proved that the inductance method is effective.
