Analysis of Excitation Field of Superconducting Linear Motor for Electromagnetic Ejection

The thrust of the electromagnetic ejection device is provided by a high-temperature superconducting linear motor. In this paper, the excitation magnetic field of high-temperature superconducting linear motor (HTS-LM) is analyzed in detail. The excitation magnetic field of HTS-SM was analyzed in detail using the Bio-Savard law. Finally, the magnetic field analysis at different positions of the superconducting excitation coil was carried out by using finite elements.
