Abstract :
Sensorless vector control of an interior permanent magnet synchronous motor (IPMSM) has been studied in many papers. The extended electromotive force (EMF) based method is one of the representative systems. We proposed a simplified method which estimates the rotor position using the controlled voltage without using observer. In this paper we have compared these methods through trajectories of poles and experimental transient responses for stability study.
