CORE LOSS ANALYSIS OF THE RELUCTANCE SYNCHRONOUS MOTOR WITH BARRIER ROTORS

Peter Hudák - Valeria Hrabovcová - Pavol Rafajdus - Jozef Mihok

   This paper presents a numerical method for the core loss calculation based on the FEM. Magnitudes of the magnetic flux density in individual segments of the machine are gained by means of FEM. On the basis of Fourier analysis of the flux density waveform the core loss is calculated for a given value of voltage or current. This method is applied to a reluctance synchronous motor (RSM) with a barrier rotor. At the end, the core loss versus supplied voltage is calculated and compared with the measured values. The coincidence is very good.
