Analysis and Implementation of Two Phase Flux Reversal Free Doubly Salient Machine
Prabhu Sundaramoorthy,Balaji Mahadevan 한국자기학회 2018 Journal of Magnetics Vol.23 No.3
The major factors that limit the application prospects of Switched Reluctance Motor (SRM) include torque ripple, noise and vibration. The main reason attributed to these drawbacks is the nature of flux linkage variation in accordance with rotor position. In this aspect this work analyses the effect of embedding permanent magnets in the stator and the impact of their orientation on the flux linkage characteristics and hence on the performance of the motor. In addition the effect of lamination material on the characteristics of the motor is analysed. The materials considered include M850-65A, M-19, M-43, Pure Soft Iron, and M800-50D. This paper proposes, the optimization of Permanent Magnet Flux Reversal Free Switched Reluctance Motor (PMFRFSRM) through the orientation of permanent magnets and choice of suitable laminating materials to improve the performance characteristics of the motor. The analysis is performed using Finite Element Analysis (FEA) based package MagNet and the results are validated with hardware prototype.
