A Coaxial Magnetic Gear With Consequent-Pole Rotors
IEEE Transactions on Energy Conversion, 2017In this paper, a novel coaxial magnetic gear (MG) is proposed, in which both permanent magnet and consequent poles are employed on the inner and outer rotors. The MG is expected with improved torque transmission capability by increasing the effective magnetic flux and offering additional reluctance torque.

An improved coaxial magnetic gear using flux focusing
2011 International Conference on Electrical Machines and Systems, 2011This paper presents a new topology of the coaxial magnetic gear (CMG) in which the permanent magnets (PMs) in the outer rotor are magnetized in tangential direction, hence offering the flux-focusing effect. By using the 2D finite element method, the influence of the main design parameters on the maximum pull-out torque of the proposed magnetic gear is ...

Comparison of Radial Force at Modulating Pieces in Coaxial Magnetic Gear and Magnetic Geared Machine
IEEE Transactions on Magnetics, 2018Unlike the coaxial magnetic gear (CMG), the magnetic geared machine (MGM) has the ac armature winding on the inner part or the outer part. Besides, the PM excitation field of the CMG and the ac armature field of the MGM have different space harmonic components of magnetic field from one other.
