Analysis of Switched Reluctance Machines using Opera FEA Webinar

Published on 16 Jun 2015

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. […]
