Electromagnetic design of a fault tolerant electromechanical actuator for landing gear

Clean aviation is a term that have been used more and more for some years now, more than a simple term is a mission prosecutable with More Electric Aircraft and All Electric Aircraft for greenhouse gas reduction. Electromechanical actuators represent key components for the replacement of actual pneumatic and hydraulic actuation systems, but the reliability is an important factor to take in account. In this paper an innovative and promising architecture of fault tolerant electromechanical actuator and the design process of electric motors for landing gear actuators for a small aircraft is presented.
