Characterization of the Parameters of Interior Permanent Magnet Synchronous Motors for a Loss Model Algorithm

The paper provides the results of a detailed experimental study on the variations of the characteristics of an interior permanent magnet synchronous motor, when load, speed and/or magnetization conditions vary. In particular, the characterization is carried out by assessing, for several working conditions, the motor parameters that influence its efficiency. From the knowledge of the variability...

Phase-Inductance-Based Position Estimation Method for Interior Permanent Magnet Synchronous Motors

This paper presents a phase-inductance-based position estimation method for interior permanent magnet synchronous motors (IPMSMs). According to the characteristics of phase induction of IPMSMs, the corresponding relationship of the rotor position and the phase inductance is obtained. In order to eliminate the effect of the zero-sequence component of phase inductance and reduce the rotor positio...

Parameter Identification of Permanent-magnet Synchronous Motors for Sensorless Control

An online parameter identification method is proposed for sensorless control for surface and interior permanent-magnet synchronous motors (SPMSMs and IPMSMs, respectively). As this method does not use rotor position or velocity to identify motor parameters, the identified parameters are not affected by position estimation error under sensorless control. The proposed method that is based on syst...
