This paper proposes a useful method to estimate the initial mover position of a surface-mounted permanent magnet linear synchronous motor (SPMLSM). The estimation is performed by saliency effect and nonlinear magnetization characteristics of stator core. Two available methods of pulse voltage injection and high-frequency injection are analyzed in detail, and then a relatively simple approach in signal processing is proposed. By the measurement of a SPMLSM prototype, the high-frequency injection method is proved more accurate and reliable than pulse-voltage injection method in estimation of the initial mover position.
