Abstract The paper presents the research on evaluation of accuracy of magnetic field calculations of synchronous reluctance motor in comparison with the results obtained in experiments. Magnetic field calculations are performed with the finite element method to determine values of the magnetic flux and electromagnetic torque according to the current value in motor stator and load angle between the rotor direct-axis and axis of stator magnetomotive force (MMF). Experimental values of magnetic flux and electromagnetic torque are obtained on motor with locked rotor while equivalent direct current is applied to the stator windings. The research shows that the results obtained from the magnetic field calculations coincide well with the experimental data.

The rare-earth (RE) permanent magnets (PM) have been increasingly adopted in traction motor application. However, the RE PM is expensive, less abundant, and has cost uncertainties due to limited market suppliers. This paper presents a new design of a RE-free five-phase ferrite permanent magnet-assisted synchronous reluctance motor (Fe-PMaSynRM) with the external rotor architecture with a high saliency ratio. In such architecture, the low magnetic coercivity and demagnetization risk of the ferrite PM is the challenge. This limits the number of flux barriers, saliency ratio, and reluctance torque. A precise analytical design procedure of rotor and stator configuration is presented with differential evolution numerical optimizations by utilizing a lumped parameter model. A 3.7 kW prototype is fabricated to validate the proposed idea.
