Reluctance Network Analysis of High Power Synchronous Reluctance Motor with Saturation and Iron Losses Considerations

This paper provides a reluctance network modeling for the steady state performance calculation of a 94kW massive or a 125kW flux barrier rotor synchronous reluctance machine. The massive rotor is suitable for high-speed application; the flux barriers increase the saliency ratio and lead to higher torque and power factor. The suggested model is significantly faster than finite element method and is precise as for performance criteria such as torque and power factor. This precision is guaranteed by taking into account the saturation of all ferromagnetic parts of the machine. The proposed model also permits to compute the stator iron losses and consequently the motor efficiency.
