A comparative study of the performance of DC permanent magnet and AC induction motors in urban electric cars

This paper presents a comparative study of the performance of two types of electric motors used in eco-urban electric cars (EC). The power transmission system of an EC is modelled once with a DC permanent magnet (PM) and once with an AC induction motor (IM). In both cases the electric motors can operate in two modes: propulsion mode (motor) and regenerative brake mode (generator). Two standard velocity history profiles SFUDS and ECE-15 are used to model the dynamic of the car. It is shown that IM performs more effective than PM.
