Comparison of Three Different In-Wheel SMPM Motor Configurations Based on the Urban NEDC

Abstract:

Design optimization of traction motors for light electric vehicles over an operating point is an adequate way of achieving higher overall efficiency under a standard driving scheme of the vehicle. However, this work proves that a direct comparison of similar candidates regarding efficiency values under a predetermined operating point does not yield sufficient information on the economy achieved on a specific driving pattern per candidate. This paper presents a comparative study on three similar surface mounted permanent magnet in-wheel motor configurations. On a first step, these configurations are compared in terms of efficiency and performance over one operating point. On a second step, efficiency maps of the designs under study are utilized to provide a wider picture of their efficiency attributes. On the final step, the three configurations are simulated driving a prototype light electric vehicle in the Urban part of the New European Driving Cycle and the results are discussed.
