Abstract

The propulsion system of road vehicles could be realized with the use of electric motor and a transmission system. Complex analysis of these systems has been the topic of many recent researches, so an existing drive train has been chosen. The systems in this paper consist a permanent magnet 3 phase synchronous motor and switchable, continuously variable as well a constant ratio propulsion system. The most important variables in this study are the torque, RPM and power of motor, the combined efficiency dimensions and mass of drive train, vehicle mass, speed levels, mode and way of vehicle use. Our target is to create such a drive train, which has the best efficiency and lowest weight at a defined power level.
