Title: Analysis and Testing of a Coaxial Magnetic Gearbox With Flux Concentration Halbach Rotors

Abstract

Halbach array magnetic gearboxes have been discussed as being able to create high torque density. However, Halbach arrays are difficult to mechanically assemble, and often the effective air gap must be made larger to provide space for a retaining sleeve. This paper investigates here the benefits of using an additional ferromagnetic retaining pole within the Halbach array structure. It is shown that utilizing this flux concentration ferromagnetic pole improves the torque density and can also help retain the magnets in place.

Magnetic gearbox with flux concentration halbach rotors

Patent Bird, Jonathan

This application relates to translating mechanical energy from a low-speed rotor to a high-speed rotor or vice versa in a magnetic gearbox. More specifically, this application discloses various embodiments of a coaxial magnetic gearbox with flux concentration Halbach rotors. In certain implementations, the device further comprises a circular back iron (or other ferromagnetic material) disposed concentrically along the axis of the cylindrical magnetic gearing device. In such embodiments, this flux concentration back iron (or ferromagnetic pole) improves the torque density and can also help retain the magnets in place.

Investigating the Performance of a Fully Laminated Flux-Focusing Magnetic Gearbox

Journal Article Li, Kang ; Uppalapati, Krishna Kiran ; Wright, Jason ; ... - Progress in Electromagnetics Research C

This paper presents here the design investigation and experimental testing of a flux-focusing magnetic gearbox with a fully laminated rotor structure. The unique feature of this flux-focusing magnetic gearbox design is that the three rotors are each made of a single lamination stack, and the central modulation structure is retained in place without the use of a resin filler such as epoxy. Ferromagnetic bridges are used to connect individual pole pieces together. It is shown that the use of the ferromagnetic bridges reduces the calculated torque density from 156 Nm/L to 139 Nm/L (a reduction of 11%). The experimentally measuredmore »« less

Electromagnetic analysis and experimental testing of a flux focusing wind turbine magnetic gearbox

Journal Article Li, Kang ; Modaresahmadi, Sina ; Williams, Wesley ; ... - IEEE Transactions on Energy Conversion

The electromagnetic design of the second stage of a 59:1 multistage magnetic gearbox for a wind turbine demonstrator is presented here. The multistage series connected magnetic gearbox is composed of a 6.45:1 first stage and 9.14:1 second stage magnetic gear. The magnetic gears utilize a flux focusing spoke type rotor typology with a unique segmented fully laminated design. The electromagnetic impact of structural design changes on the second stage gearbox is considered with respect to torque density. Severe 3-D edge effects were encountered that greatly reduced the expect torque density of the stage 2 magnetic gear. Experimental testing of themore »« less

A comparative analysis of torque production in Halbach and conventional surface-mounted permanent-magnet synchronous motors

Conference Ofori-Tenkorang, J ; Lang, J H

The general question of when and why one should use a Halbach rotor in the design of surface-mounted permanent-magnet synchronous motors is addressed. The torque production capabilities of Halbach and conventional magnet arrays under the constraints of fixed magnet volume, and fixed power dissipation in slotless armature windings, are compared and the results presented in a graphical manner along with intuitive models that qualitatively explain these results. They conclude that, for permanent-magnet synchronous motors where the application precludes the use of a magnetic back-iron, the Halbach array always produces higher torque than the conventional array, for the same volume ofmore »« less
Designing and Experimentally Testing a Magnetic Gearbox for a Wind Turbine Demonstrator

Journal Article Li, Kang ; Modaresahmadi, Sina ; Williams, Wesley ; ... - IEEE Transactions on Industry Applications

Here, the design of the first stage of a 59:1 multistage magnetic gearbox for a wind turbine demonstrator is presented here. The multistage magnetic gearbox (MSMG) is composed of a two stage magnetic gearbox (MG). The first stage of the MSMG has a gear ratio of 6.45. A spoke type MG rotor typology is used with a unique segmented fully laminated rotor structure. Axial-ly segmented magnets and a unique set of radial deflection rotor support rings are utilized. Design issues with respect to losses and torque ripple are highlighted.
