Abstract

The aim of this paper is to introduce - by general analytical nonlinear and then optimal design with vector control a hybrid electric and electric vehicles (HEV/EV) electric propulsion system for 50/100 kW, 1350-7000 rpm (600 Nm peak torque/40 kg) at above 91% overall efficiency 300 Vdc battery for a peak phase current of 520 A. After searching quite a few alternative electric machines the low weight (40 kg) NdFeB (1.1 T) PM-Reluctance synchronous machine with vector control was developed in detail. Finite element validation of flux density, torque, inductances and non-reconfigurable vector control for the entire peak torque (power) very challenging envelope substantiate a moderate cost high performance HEV (EV) drive.
