Abstract

This paper introduces position-sensorless speed control of surface mounted permanent magnet synchronous motors (SPMSMs) based on an extended electromotive force (EMF) and specifically focuses on performances at very low and medium speeds. According to Authors’ best knowledge, Morimoto’s extended EMF approach is firstly applied to SPMSM and its low speed operation is evaluated by computer simulations and real-time experiments in the scope of this paper. To show that Morimoto’s extended EMF technique is suitable to SPMSMs, computer simulations are executed in MATLAB® Simulink. Later, real-time experiments are performed to confirm the effectiveness of the proposed position-sensorless control system embedded on dSPACE-DS1104 controller with the SPMSM of 0.0262 Vrms/rpm. The resulting performance reveals that the possible speed estimation and thus position-sensorless control can be realized down to 1.4286% of the rated speed.
