Optimization of the Superconducting Halbach Array

2020
This Chapter presents the further optimization of the coil locations and the number of coils, to obtain a better homogeneity of the magnetic field in the centre area of the superconducting Halbach Array, on the premise of maintaining the total amount of superconducting material used.

CHAPTER 5. Hardware Developments: Halbach Magnet Arrays

2015
Halbach magnet arrays are very attractive for mobile NMR, because they generate very homogeneous and strong magnetic fields per magnet mass and have negligible stray fields. First of all, they are introduced as idealized geometries. Then the problems arising from the practical necessity to truncated and discretize the ideal Halbach is discussed in ...

Halbach Array for an in- Wheel Traction Motor

2018 XIII International Conference on Electrical Machines (ICEM), 2018
This paper compares a Halbach array to a more conventional surface mounted permanent magnet arrangement for an in wheel traction motor. Demagnetisation, physical air-gap and torque capability at continuous and overload operation is considered. Without increasing the machine operating space, using one transition per pole was found to increase rated ...

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 ...

Design of Multilayer Winding-Based Halbach Array PM Compulsator

IEEE Transactions on Plasma Science, 2023
Compulsator provides higher energy density and comparable power density for pulse power supply than capacitor-based sources. With the added feature of natural current, zero-crossing capabilities make compulsator the ideal choice for pulse power supply to
