Axial position estimation of conical shaped motor for green taxiing application [PDF]
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016 This paper considers the possibility of adopting a conical shaped motor for Green Taxiing (GT) application. This topology of motor has been selected in order to obviate the presence of external declutching system (i.e. mechanical or electromagnetic clutch) interposed between the electric actuator and the wheel.
