Further Developments in the Production of an Innovative Motor Concept with Radially Laminated Stator Sheets and Flux Barriers

Abstract

In the course of saving resources and energy caused by factors such as environmental protection and the climate crisis, various motor topologies are being developed and investigated continuously. One of these developments is being promoted by researchers at the EAA and IWU and concerns the implementation of an innovative motor concept with radially laminated stator steel sheets and flux barriers. Various new developments in design and manufacturing technology have to be implemented as well as analyzed for this new development. This paper provides an insight into the electromagnetic relationships within the newly arranged grain-oriented laminations as well as findings from the production of the first prototypes. Furthermore measurement results on the electromagnetic behavior of the stator are given as well as subsequent findings and derived decisions are presented.
