Abstract—As the mechanical sensor of PMSM easily break out, attentions are paid to the PMSM sensorless control method. In this paper, a modified stator flux methods based on the active flux is proposed, which can estimate the rotor position and speed of the motor after accurate stator flux estimation using active flux. This method is of simple calculation and less dependence on motor parameters, and it suits for both SPMSM and IPMSM. The simulation results and experimental results show the method can estimate both the rotor position and speed in either abrupt load torque or variable speed condition.
