Abstract

Three different motor topologies, (1) radial, (2) axial and (3) transverse flux, are investigated for ´in-wheel´ electric propulsion system. The design constraints are: 350mm×100mm package limitation, 48 V DC bus restriction and per phase inverter current limited to 500 A^pk. In addition, magnet pole pairs are fixed to 9 due to limitation in ´position sensor´ capacity. The paper summarizes results obtained from analytical design followed by 2D and 3D static and transient finite element analysis accompanied with experimental verification for the radial flux topology.
