Abstract
- In this paper, a new eccentricity compensation method for Switched Reluctance Machines (SRMs) is presented. In this regard, the dependency of radial force (RF) on variation of number of turns for stator coils and fault level is demonstrated analytically and principle of the new compensation strategy is introduced as well. This strategy is implemented on an SRM utilizing Finite Element Method (FEM) under different fault conditions. This approach is accomplished through switching among the various arrangements in the number of turns for the coils on the stator poles; hence, unbalanced magnetic force (UMF) is controlled without additional auxiliary coils. Simultaneously, regulating the stator currents guarantees the motor torque is not diminished. This comprehensive approach is suitable for different types and structures of SRMs and will compensate or control eccentricities in a wide range of eccentricity faults namely 10%-70% while motor performance is not impaired.
