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.
