Abstract :
This paper proposes an extended-flux model with core-loss resistance of synchronous reluctance motors (SynRMs) and precise torque estimation without core-loss measurement and position encoder. The proposed torque estimation is useful for precise maximum torque per ampere (MTPA) control of position sensorless controlled SynRMs, which is achieved with the assistance of active and reactive powers.
