Nowadays, the research and industry societies showing their interest on permanent magnet assisted synchronous reluctance motors. One of the main disadvantages of using permanent magnets in electrical machines is a risk of demagnetization. This paper discusses a hybrid FEA-Simulink model with damaged permanent magnets in rotor flux barriers. Three sets of interpolation tables were computed using two-dimensional finite element analysis, calculated flux linkages and electromagnetic torque were used for development of Simulink model. Proposed model gives more accurate results in comparing to analytical one. The model opens the possibility of studying the machine under more realistic situations.
