Characteristics analysis of a transverse flux permanent magnet motor using two fast permeance models

This paper discusses the use of two different fast ways to study a novel in-wheel permanent magnet motor for a vehicle direct drive: the Transverse Vernier Hybrid Reluctance Motor (TVHRM). The geometry of the magnetic circuit of this latter is especially 3D. The use of the 3D finite element method to do the analysis and to predetermine the motor characteristics is more accurate, but with an important computational time which makes unpractical a parametric study. An analytical model which will allow a rapid investigation of the motor characteristics is a good compromise between accurate results and a weakly simulation time. This is done through two comparable models based both on the equivalent reluctance network method. The predicted characteristics are compared with the practical test results.
