Novel cooling concept for eco-friendly mobility

Making electric cars lighter and reducing the weight of the motor.

One way to do that is by constructing it from fiber-reinforced polymer materials. 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 motor housing materials. And that’s not the only advantage of the new cooling concept: it also significantly increases the power density and efficiency of the motor compared to the state of the art.
