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. In one study, they found that the aluminum coils increase the continuous output of the electrical machines compared to the copper windings, reduce the operating temperature and at the same time save weight and raw material costs.
