This paper investigates the performance of a -25:1 gear ratio cycloidal magnetic gearbox (CMG) with a flux-focusing rotor topology. The performance of the CMG is investigated by conducting an iterative...

This digests presents the closed form 3-D analytical equations for an axial and radial Halbach rotor magnetic coupling. The closed form equations give insight into the upper torque density limits of NdFeB based...

A 3-D analytical model is presented for a Halbach axial magnetic coupling. The field and torque are determined by first solving a 2-D field problem at the radial location in which the radial flux density is...

This paper derives the closed form 3-D analytical torque equations for an ideal radial Halbach rotor magnetic coupling. The performance of the radial Halbach coupling is then compared with an ideal axial...

This paper presents the design investigation and experimental testing of a flux-focusing magnetic gearbox with a three piece laminated rotor structure. Each rotor is made of a single lamination stack held...

Halbach array magnetic gearboxes have been discussed as being able to create high torque density. However, Halbach arrays are difficult to mechanically assembly and often the effective air-gap must be made...
