Dr-Ing. Martin Doppelbauer, Professor for HEVs at the Karlsruhe Institute of Technology (KIT), will use his seminar at CWIEME Berlin to reveal three alternative electric motor designs together with their test results. “It’s all about power density,” said Dr. Doppelbauer. “If we can develop motors for EVs with the same or higher power and torque at a smaller size and weight, then we can significantly reduce engine cost.”
