The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent Magnet Linear Synchronous Motor (PMLSM) can provide high instantaneous thrust. This paper presents the design and analysis...

Optimization methods are presented to design Halbach arrays to maximize the forces applied on magnetic nanoparticles at deep tissue locations. In magnetic drug targeting, where magnets are used to focus therapeutic nanoparticles to disease locations, the sharp fall off of magnetic fields and forces with distances from magnets has limited the depth of targeting. Creating stronger forces at depth...

An analytical technique is developed for predicting the performance of a bonded Halbach oriented anisotropic magnet, with due account of partial alignment of the NdFeB powder during injection molding. The predicted performance of a 12-pole injection molded, Halbach oriented magnet is compared with measurement.

In this paper, an analytical analysis is presented to calculate air gap flux density distribution, thrust and efficiency in air-core permanent magnet linear synchronous motor with Halbach array based on Maxwell equations. In order to improve mean thrust, thrust ripple, magnet and copper consumption, the main design parameters of analyzed machine are optimized by using genetic algorithm in an ap...

Hybrid subdomain analysis is utilized to optimize the design of a high-speed compressor motor. Permanent magnets (PMs) are arranged in Halbach array and bounded by carbon fiber sleeve. The stator core does not have slot structure, so that it advantageous reducing iron loss. Since saturation takes place, magnetic equivalent circuit (MEC) used find permeability depending on flux density yoke. Fur...
