Motor and Drive Design for eVTOL Aircraft
Proceedings of the Vertical Flight Society 80th Annual Forum and Technology DisplayThe design of a powertrain for an eVTOL is a complex, multidisciplinary challenge whose solution is best approached as a constrained optimization problem. We use a motor and drive optimization tool based on both first principles and empirical models to examine the design space for a medium-sized eVTOL aicraft.
