In this paper, a superconducting augmented rail-type electromagnetic launch system (SAREML) is proposed due to its inherent advantages in terms of lower current, smaller rail ablation, higher propulsive force, and higher energy efficiency. A superconducting coil to enhance the magnetic field was designed and analyzed. The inductance was calculated using the finite element method. Then, the mathematic...
In this paper we design a three-phase tubular permanent magnet linear motor for high speed lifting application. Analytical formulas are derived to predict the magnetic field distribution, magnetic flux linkage, induced electromotive force, total force and current. The major design parameters are optimized by the analytical solution to meet the performance requirement of the linear machine. The final...
