The Design and Simulation of a Novel Electromagnetic Launcher with Permanent Magnet

Abstract

This paper presents a novel electromagnetic launcher (coil gun) with permanent magnet (PM) as the projectile. The design, calculate and simulation of the PM coil gun are described. The excitation switching sequence of the coil and the performance of the novel coil gun including the electromagnetic force and speed of the projectile are presented accordingly. It is concluded that this novel coil gun with permanent magnet can achieve high speed of projectile within smaller package and with less energy consumption.
