Magnetomechanics of internal-dipole, Halbach-array motor/generators

IEEE Transactions on Magnetics, 2000
The magnetomechanical behavior of internal-dipole, Halbach-type magnet arrays is analyzed for application as a motor/generator (M/G) with an energy-storage flywheel that is suspended by low-stiffness bearings. Scaling laws for the maximization of torque are derived as a function of geometry.

Four Cylinder Halbach Array for Magnetic Navigation System

2009 3rd International Conference on Bioinformatics and Biomedical Engineering, 2009
The magnetic navigation system has been widely used for the minimally invasive interventions. The four cylinder Halbach array was introduced into the magnetic navigation system to decrease the high cost. A small model was manufactured and measured. The experiment results indicated that the orientation of magnetic field could be precisely controlled by ...

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 ...

Energy harvesting from electric power lines employing the Halbach arrays

Review of Scientific Instruments, 2013
This paper proposes non-invasive energy harvesters to scavenge alternating magnetic field energy from electric power lines. The core body of a non-invasive energy harvester is a linear Halbach array, which is mounted on the free end of a piezoelectric cantilever beam.

Research and simulation of an improved Halbach arrays

2011 International Conference on Electric Information and Control Engineering, 2011
Halbach array is new permanent structure. It was proposed by physicist Dr. K. Halbach of the U.S. Lawrence Berkeley National Laboratory. This paper proposes an improved magnet structure of Halbach array. By simulation of finite element software-Ansoft's Maxwell, the results show that improved magnet structure can effectively improve the uniformity of ...

Partitioned stator flux reversal machines having Halbach array PMs

2015 IEEE Magnetics Conference (INTERMAG), 2015
Purpose – In this paper, the partitioned stator flux reversal permanent magnet (PM) (PS-FRPM) machines with Halbach array PMs are investigated to compare with the machine having the conventional parallel magnetized PMs, and conventional FRPM machine. This paper aims to discuss these issues.
