摘要：
A novel method based on the saturation effect to estimate the rotor initial position of a brushless direct current motor at standstill is presented in this paper. The rotor initial position can be estimated by comparing the magnitude of the stator current vector through setting up voltage space vector. Motor wear reduction and acceleration of the motor up will be realized due to this novel method. Simulation results confirm this method is effective and precise with the maximum estimated error of the initial rotor position can be controlled within 1 degrees. (c) 2011 Published by Elsevier Ltd.
