Abstract
The disclosure presents configurations and analyses of magnetic gears, which may be used in the second stage of a multistage magnetically geared generator for a marine hydrokinetic generator application and/or other applications as described. In order to reduce field harmonics and maximize the torque density, a Halbach rotor topology is utilized. One feature of the disclosed configuration is a unique magnet arrangement that enables inner and outer Halbach rotor magnets to be more easily assembled, even with dimensional tolerance inaccuracies. The disclosed Halbach magnet rotor topology makes use of the internal magnet forces to retain the magnets in position, and the disclosed configuration also helps with the assembly process.
