摘要：

This paper presents a new standstill rotor position detecting algorithm for non-salient permanent magnet synchronous machine(PMSM) without any position sensor. By injecting high frequency current to the stator of the machine, the proposed algorithm provides the standstill rotor position with reasonable accuracy as well as the direction of magnetization. Though this paper focuses on the non-salient PMSM, the proposed algorithm also works more effectively in case of the salient machine such as interior permanent magnet machine. From the experiments the standstill rotor position is successfully defected within +/-5 degrees error in electrical degree.
