Title: Designing and Experimentally Testing a Magnetic Gearbox for a Wind Turbine Demonstrator

Abstract

Here, the design of the first stage of a 59:1 multistage magnetic gearbox for a wind turbine demonstrator is presented here. The multistage magnetic gearbox (MSMG) is composed of a two stage magnetic gearbox (MG). The first stage of the MSMG has a gear ratio of 6.45. A spoke type MG rotor typology is used with a unique segmented fully laminated rotor structure. Axial-ly segmented magnets and a unique set of radial deflection rotor support rings are utilized. Design issues with respect to losses and torque ripple are highlighted.
