A Coaxial Magnetic Gear With Halbach Permanent-Magnet Arrays [PDF]
IEEE Transactions on Energy Conversion, 2010 This paper proposes a coaxial magnetic gear that offers higher torque density, lower cogging torque, and lower iron losses than its counterparts. The key is to newly employ a Halbach permanent-magnet (PM) array to constitute the PM poles in the inner rotor and a partial Halbach array (two segments per pole) for the outer rotor.

Comparison of Coaxial Magnetic Gears With Different Topologies [PDF]
IEEE Transactions on Magnetics, 2009 This paper quantitatively compares two coaxial magnetic gears (CMGs) with different topologies, namely, the CMG installed with radially magnetized permanent magnets (CMGRM) and the CMG installed with Halbach magnetized permanent magnets (CMGHM). By using the 3D finite element method, the end-effect and the performances of both CMGs are investigated ...

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

Magnetic Loss Analysis in Coaxial Magnetic Gears [PDF]
Electronics, 2019 This paper proposes a procedure for computing magnetic losses in coaxial magnetic gears. These magnetic structures are made of permanent magnets and ferromagnetic poles in relative motion transferring torque between two shafts in a contactless way. The loss computation in magnetic materials is crucial to define the system performance.
