Abstract
Line Start Interior Permanent Magnet Synchronous Motors became competitors to cage induction motors in the general purpose industrial applications for their zero steady-state speed regulation, high efficiency and high power factor as well as for their ability to self-start from the regular fixed frequency supply. However, these motors suffer from parameters variation during operation due to the temperature fluctuations of the permanent magnet and saturation to the stator iron core. The paper uses the wellknown time harmonic finite element analysis to study some performance characteristics of one of these commercial motors considering these changes. Moreover, the problem of PM irreversible demagnetization due to abnormal armature reaction is studied for the same motor.
