Electro-thermal topology optimization of an electric machine by the topological derivative considering drive cycles

Nepomuk Krenn, Théodore Cherrière, Sebastian Schöps +1

We consider a 2d permanent magnet synchronous machine operating in a sequence of static operating points coming from a drive cycle. We aim to find a rotor design which maximizes th…
