摘要：

A sensorless brushless DC (BLDC) control algorithm based on rotor saliency is proposed in this paper. A voltage pulse injection method is used for inductance measurement and the peak inductance current is measured through the salient phase to increase accuracy. Zero speed and arbitrary low speed sensorless operations can be achieved with the proposed algorithm. Finite element analysis method (FEM) simulations and experimental results are provided to verify the proposed control algorithm.
