Performance Analysis of Single Inductive Coil Driver

The performance of a single inductive coil driver with six different turns of drive coils is analyzed and emulated with the emulation program in this paper. Under the condition that the integral projectile mass is 1.125 kg and the armature length is 300.0 mm, the maximum velocities of the projectile are 130.1, 134.1, and 132.8 m/s when the drive coil axial lengths are 50.0, 100.0, and 150.0 mm, respectively, and the drive coil radial thickness is 20.0 mm. By changing the drive coil radial thickness to 30.0 mm, the maximum velocities of the projectile are 112.5, 110.2, and 116.3 m/s when the drive coil axial lengths are 50.0, 100.0, and 150.0 mm, respectively. The result shows that only when the structural parameters of the drive coil and the armature are matched suitably that the maximum velocity of the projectile can be reached. This conclusion provides a reference for the engineering practice of the inductive coil driver.
