Performance Evaluation of Single Phase Flux Switching Reluctance Machine for Low Cost Turbo Machinery

Single Phase Flux Switching Reluctance Machines (SPFSRMs) are characterized by rugged structure, low cost and high reliability for high speed operation despite its poor starting capability. An analytical approach of performance evaluation for a 8/4 pole SPFSRM is developed in this paper. Firstly, using a lumped magnetic circuit model, the static performance is obtained. Then, a high precision saturated inductance model is constructed which can take the specific saturation effects and substantial influence of field current into consideration. At last, the motor transient performance can be precisely predicted in terms of winding current, torque and speed. A 2kW 8/4 pole prototype SPFSRM is designed together with the experimental correlation.
