Abstract

The TRAX project aims at developing a generation of electric motors (7.5 to 15 kW) for the automotive power trains. The vehicles covered are “all electric” without gearbox in the range of heavy quadricycle. The two objectives of this project are to: i) design an innovative axial flux PM motor (AFPMM) and industrially feasible in series, ii) use an analytical model (AM) based on reluctances networks (i.e., the magnetic equivalent circuit) in order to design an optimal electric motor. The electromagnetic design by AM has enabled us to achieve a first prototype of AFPMM. The analytical results are compared to those experimentally obtained.
