Comparison of three different electric powertrains for the use in high performance Electric Go-Kart

For propulsion of electro and hybride vehicles basically 3 different motors are used: induction machine (IM), permanent synchronous machine (PM) or switched reluctance machine (SR). To analyse and compare these types of machines three electrically powered go-karts were buildt at Daimler Chrysler AG Stuttgart plant 10. These e-go-karts have the same configuration regarding batteries, power inverter, gearbox and mechanical parts. To compare MATLAB/SIMULNK simulations with measurement data sampled on a race track a data logging device with sufficient data storage is built in. The present publication describes the impact of the efficiency characteristic map of these three electric machine types with identical construction sizes and the performance in the e-go-karts.
