A Novel Drive Train Concept for Personalized Upper Body Exoskeletons with a Multiphase Axial Flux Machine

This paper deals with a novel drive train concept for a personalized exoskeleton power module, which can be used in industrial production or construction applications. To match the personal needs of individual user, a modular and rapidly designable concept is introduced. A topology comparison for different machine concepts has been done and a multiphase double-sided axial flux machine concept with an integrated planetary gear is presented. An analytical model approach for a fast electrical machine design process is presented, to calculate the torque performance of the power module. In the end, a three dimensional FE simulation is presented to verify the analytical models.
