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...
The eddy current induction in a conductive medium with finite width and thickness due to a moving magnetic rotor is studied. The presented formulation is based on the second order vector potential and the...
The purpose of this paper is to present the derivation of a 3-D analytical solution of a null-flux electrodynamic suspension device for a conductive plate. The device consists of a linear Halbach magnet array...
By translationally moving a magnetic source above a conductive plate guideway both levitation and drag forces are created. Unfortunately, the electrodynamic drag force can be quite high [1]. Kratz studied a...
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...
In this paper the concept of magnetic rolling resistance (MRR) is introduced. The MRR is particularly useful when trying to characterize maglev devices that operate with a slip. Approaches to minimize the MRR...
This paper investigates the performance capabilities of a continuously variable magnetic gearbox that utilizes a flux focusing rotor structure. A fractional slot stator winding is designed to couple to the...
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...
