Researchers at the Fraunhofer Institute for Chemical Technology ICT are working together with the Karlsruhe Institute of Technology KIT to develop a new cooling concept that will enable polymers to be used as EV electric motor housing materials, thereby reducing the weight of the motor and thus, the EV itself. The new cooling concept also significantly increases the power density and efficiency of the motor compared to the state-of-the-art. Sectional view of the electric motor. The core of the motor is a stator consisting of twelve individual teeth, which are wound upright using a flat wire. © Fraunhofer ICT Three issues that play a particularly important role when it comes to using an electric motor for mobility: high power density; a compact configuration that fits snugly within the electric vehicle; and high levels of efficiency. As part of the DEmiL project—Direktgekühlter Elektromotor mit integralem Leichtbaugehäuse, or directly-cooled electric motor […]
