Design and Analysis of a New Magnetic Gear With Multiple Gear Ratios

IEEE Transactions on Applied Superconductivity, 2014
This paper proposes a new magnetic variable gear which offers different speed ratios. In order to provide the gear-ratio-changing ability, a high-remanence low-coercivity permanent magnet (PM), namely the aluminum-nickel-cobalt (Alnico), is utilized. By incorporating the concept of the magnetic gear and the concept of memory machine, a new double-deck ...
