Abstract

This paper presents the analysis and mechanical design of a 15.9kW magnetic gear (MG) with a 12.4:1 gear ratio and a computed 53 N•m/kg mass torque density. When the MG is connected in series with a high-speed motor it forms an aircraft MG drivetrain. The target specifications are based on the quad-electric aircraft propulsion system needed for hover-load conditions for NASA’s electric vertical take-off and landing vehicle.
