Design of switched reluctance machines for industrial applications

Switched Reluctance Machines (SRMs) applied in adjustable speed drives are receiving during the last two decades considerable attention from industry since they are characterised by rigid construction, high operation reliability, high efficiency and last but not least low manufacturing costs. The successful realization of a SRM drive for industrial application demands inter alia of the determination of the best motor construction from the point of view of the requirements of considered drive. A new hybrid design method for SRM drives with application of analytical calculation methods, finite element method and simulation models is proposed in this paper. The calculation/design system is characterised by important effectivity and reliability. The correctness of the proposed design algorithms is verified by laboratory tests made on two motor prototypes manufactured for concrete industrial applications.
