Fraunhofer researchers develop technique to produce aluminum windings for motors

Green Car Congress

To show this in a direct comparison, the Fraunhofer team used 250W commercial pedelec motors. The aluminum coil can deliver the resulting heat better to the laminated core and thus to the environment. Rebuilt engines with different laminated cores and coil combinations were tested on a bench. © Fraunhofer IFAM.
