Model-Based E-Drive Dimensioning

Setting up an efficient e-drive system that fulfills customers' requirements represents a challenging task. For this purpose, the electrical machine and the power electronics have to be dimensioned appropriately. In this process, many aspects such as efficiency, thermal behaviour, electrical performance, lifetime of the components, and derating concept have to be considered. The electrical machine and the power electronics influence each other as well as the many other components of the driving system.

It is unavoidable to perform measurements and expensive tests to evaluate the performance of the entire e-drive systems. At ZF, we try to reduce measurement costs and to make predictions based on simulation models.

In this talk, we give a short overview on the different aspects of correct e-drive dimensioning and how simulation tools, especially MATLAB^® and Simulink^®, enable engineers to accomplish the complex processes of designing a good e-drive system.
