Cost-Effectiveness Comparison of Coaxial Magnetic Gears With Different Magnet Materials [PDF]

open access: yesIEEE Transactions on Magnetics, 2014
This paper presents a comparative study between the nonrare-earth PM and rare-earth PM-based coaxial magnetic gears. First, using finite-element analysis, the electromagnetic performances of four coaxial magnetic gears, which are installed with nonrare- or rare-earth PMs, are analyzed and quantitatively compared based on the same structure.
