Analysis of Switched Reluctance Machines using Opera FEA Webinar

This webinar presents the use of the Opera Finite Element Suite and the dedicated Machines Environments for the analysis and characterisation of Switched Reluctance Machines (SRM). The specific drive requirements of the SRM involve a different modelling approach than the one normally used for synchronous, sinusoidal-driven, electrical machines, with dedicated drive circuits and switching patterns. […]

Linear Motion Analysis of a Tubular Switched Reluctance Motor

This application note presents the modelling and analysis of an axisymmetric linear motor using Opera-2D. The chosen design is a four-phase tubular Switched Reluctance Motor (SRM), designed and characterized in [1]. Two types of analysis are presented using the axisymmetric model and results are compared with measured data from the actual prototype. The first analysis […]
