Researchers at Fraunhofer IFAM have developed a casting technique that can be used to produce lightweight aluminum windings with a higher groove fill factor to replace copper windings in electric motors. To show this in a direct comparison, the Fraunhofer team used 250W commercial pedelec motors. © Fraunhofer IFAM.
