Accurate Modeling and Performance Analysis of Synchronous Reluctance Motor Considering Amorphous Alloy Properties

In order to analyze the torque performance accurately, a new analytical calculation model of the high-speed Synchronous Reluctance Motor (SynRM) with the amorphous alloy core was proposed in this paper. The local effect of the amorphous alloy core on the electromagnetic properties is considered in this paper. For the proposed model, the equivalent relative permeability of the stator tooth, rotor and the air gap will be considered. So, the proposed model can be used forf motor design and optimization. Finally, the air-gap flux density and torque performance are theoretically analyzed and simulated in 4 poles symmetric structure. And there is a good consistence between the theoretical and simulation result.
