Solid-projectile helical coil electromagnetic launcher
2007 16th IEEE International Pulsed Power Conference, 2007Summary form only given. Helical coil electromagnetic launchers (HCEML's) can operate at significantly lower currents and higher efficiency in comparison to conventional railgun and induction coilgun launchers. The HCEML's versatility is due, in part, to its large inductance gradient which is typically 2 to 3 orders of magnitude greater than a ...

Optimized electromagnetic coil design theory
Proceedings IEEE Southeastcon '92, 2003The authors review the general theory of electromagnetic coil design, the starting point for which is the Biot-Savart equation, which expresses the relationship between current distribution and the resultant static magnetic field. They introduce a reformalization of the Biot-Savar equation which provides for the general design of electromagnetic coils ...

Electromagnetic Forming with Solenoid Coil
2015 Seventh International Conference on Measuring Technology and Mechatronics Automation, 2015A loose coupling method is proposed to analyze electromagnetic forming with solenoid coil. Analysis of electromagnetic field is conducted by ANSYS/Emag, structural field is solved by explicit module ANSYS/Lsdyna, and data transfer from electromagnetic field o structural field is realized by APDL program Time-space distribution of magnetic pressure and ...

Quench Detection Method for HTS Coils Using Electromagnetically Coupled Coils
IEEE Transactions on Applied Superconductivity, 2015Generally, in order to detect the quench of the superconducting field coil for the superconducting rotating machine, signal wires for voltage taps are indispensably needed. However, the problem of the conventional method is wire twisting as the superconducting field coil rotates.

Thermal analysis of electromagnetic levitation coil
2016 17th International Scientific Conference on Electric Power Engineering (EPE), 2016This paper presents analytical and numerical thermal analysis of three different toroidal coils levitated on an aluminum plate. The analytical method consists of a network of thermal resistances that make it possible to estimate the average temperature of the coils.
