The design of the second stage of a 59:1 multi‐stage magnetic gearbox for a wind turbine demonstrator is presented. The multi‐stage series‐connected magnetic gearbox is composed of a 6.45 first stage and 9.14 second stage. A flux‐focusing spoke‐type rotor typology is used with a unique segmented fully laminated design. The impact of structural design changes is considered with respect to torque density. A new rotor typology is presented that enables the magnetic gearbox to be mechanically assembled first without magnets.
