Winding Function Model of a 6/7 Variable Flux Reluctance Machine

Variable Flux Reluctance Machine (VFRM) is robust due to the fact that there isn't any windings or Permanent Magnets (PMs) on its rotor structure. Therefore, VFRMs are potential candidates for so many applications including electric vehicles and wind turbines. Consequently, developing a fast and accurate method for its electromagnetic performance analysis is essential. Although Finite Elements Method (FEM) is an accurate method, it is suffering from high simulation time. There are some other methods but they cannot easily apply to all topologies. Winding function is a fast modelling method for analyzing electric machines performance. Therefore, in this paper, Winding function modeling of a VFRM is proposed. In this regard, the concept of VFRMs and winding function modelling procedure is presented. Also, a 6 stator and 7 rotor poles VFRM is modelled by Winding Function Method (WFM) and the results are compared with the experimental results which proves that WFM is an efficient modelling and analysis tool.
