Modelling and Analysis of the Halbach Array Magnets

2019 11th International Symposium on Advanced Topics in Electrical Engineering (ATEE), 2019
The objective of this paper is the implementation through numerical modelling of Halbach permanent magnets for the determination of the optimum magnetization directions in order to obtain a uniform magnetic field around the set of Halbach permanent magnets. For this study the magnetic induction distribution, magnetic field intensity and current density

Performance of Halbach magnet arrays with finite coercivity

Journal of Magnetism and Magnetic Materials, 2016
Abstract A numerical method to study the effect of finite coercivity on the Halbach cylinder geometry is presented. Despite the fact that the analytical solution available for this geometry does not set any limit to the maximum air gap flux density achievable, in real life the non-linear response of the magnetic material and the fact that the ...

A new magnetic bearing using Halbach magnet arrays for a magnetic levitation stage

Review of Scientific Instruments, 2009
Next-generation lithography requires a high precision stage, which is compatible with a high vacuum condition. A magnetic levitation stage with six degrees-of-freedom is considered state-of-the-art technology for a high vacuum condition. The noncontact characteristic of magnetic levitation enables high precision positioning as well as no particle ...

Optimized Halbach array for focused magnetic drug targeting

Journal of Magnetism and Magnetic Materials, 2020
Abstract Magnetic drug targeting (MDT) is a therapeutic method that delivers drug carriers containing magnetic nanoparticles to a target lesion by directing them using an external magnetic field. To minimize the possible side effects on the surrounding normal cells, focused magnetic drug targeting (FMDT) has been introduced, which allows drug ...

Calculation of the Static Forces Among the Permanent Magnets in a Halbach Array

IEEE Transactions on Magnetics, 2009
This paper concerns the analysis of the interaction force among the permanent magnets (PM) in a Halbach array as used in a moving-magnet planar actuator. The goal is to analyze the magnitude of these forces and to what extent the mechanical construction of an aluminium plate, on which the permanent magnets are mounted, is deformed by the interaction ...

Analysis of axial field magnetic gears with Halbach arrays

2015 IEEE International Electric Machines & Drives Conference (IEMDC), 2015
Magnetic gears can scale the torque and speed of rotary systems, while avoiding problems associated with transferring torque through physical contact. This work uses 3D finite element analysis to parametrically characterize the performance benefits which can be obtained from applying Halbach magnet arrays to axial field magnetic gears. It is found that
