Abstract. The presentation first provides a comprehensive overview on various types of electrical vehicles (typology) together with their relevant performance characteristics so as to summarize the up-to-date topics and the state-of-the-art. A particular emphasis will be paid to the requirements of the electrical machine to be applied in the powertrain. Then energy, power and torque needs will be analyzed, and the standardized and customized duty cycles will be discussed. In the next section the calculation of the main sizes of the motor – depending on the design criteria – will be presented with a reference to the drive strategy. The current issues of AC motors will then be analyzed. More details will be provided regarding PM materials and PM motors as well as synchronous reluctance motors. An example application and a comparative analysis of different types of motors and drives for electrical vehicle applications will close the lecture.
