GM researchers push Electric Drive performance /cost frontier with high-fidelity, multi-physics tools

Today’s hyper-competitive EV market requires maximizing electric drive efficiency and performance at minimal cost. GM researchers have developed cutting-edge multi-physics 3D modeling tools to enable just that.?The trick is to manage the complicated interplay of electromagnetics (that drive machine performance) and thermal management (a key performance limiting factor). Co-simulation of electromagnetic heat generation and subsequent heat transfer enables high-accuracy prediction of magnet and winding temperatures, helping eke out maximal performance from the machine.

GM researchers are also enabling the relentless drive to reduce costs by advancing capabilities of motors free from rare-earth magnets.?First-ever high-fidelity, fast running models and analytical tools have been developed for complicated multi-winding and multi-phase electric machines. This capability is fundamental to develop controls to push the boundaries of efficiency and performance of these machines.
