Development of an aircraft wheel actuator for green taxiing

In this paper, the design and construction aspects of a wheel actuator to be used for aircraft taxiing on the ground and which will be located in the main landing gear are addressed. The main challenges with the application are the high torque density and fault tolerance requirements. This paper will look at all the different design aspects of the traction motor required for the actuator, including the electro-magnetic design and analysis, thermal management and mechanical analysis. The paper will then conclude with a brief overview of the construction aspects of the motor of the wheel actuator and experimental validation.
