A 7.5 kW Permanent Magnet Assisted Synchronous Reluctance Motor (PMASynRM) that works with ferrite magnets has been designed for a micro electric vehicle. Finite element analysis is used to evaluate machine performances and to study the demagnetization effect of ferrite PMs. An experimental validation of the PMASynRM characteristics is made. The measured values of the back electromotive force and torque are compared with the numerical predicted values. The PMASynRM electromagnetic losses are investigated in order to increase the motor efficiency.
