Analytical design and dynamic characteristics of switched reluctance motor with minimum torque ripple

Industrial interest in switched reluctance motor (SRM) drives has varied since 1850s. This has been primarily due to the emerging markets for simple design geometry and low cost in consumer and industrial products, such as home appliances, air conditioning, hand tools, fans, pump motor, etc. However, SRM has been plagued with the acoustic noise and vibration problem by input power of fixed section. Therefore, this paper offers electromagnetic analysis for torque ripple reduction between mechanical geometry and electric parameters. Also, in dynamic operating for uniform torque, the dynamic characteristics by the switching time and input current are presented. This means that the rotor pole arc and electric parameters have related to produce the active and negative torque. This analysis results are verified by the finite element method and experiment results with dynamic simulation.
