The Optimal Design of a Concentric Coil, Radial Magnet Moving Magnet Actuator

Identification of an Electromagnetic Actuator

We apply time-domain system identification techniques to an electromagnetic actuator. This actuator is part of the vibration isolation testbed at the University of Michigan.

Vladimir KINDL ELECTROMAGNETIC COIL GUN – DESIGN AND CONSTRUCTION

A single-stage, sensor less, coil gun was designed to demonstrate the capability to accelerate a ferromagnetic projectile to high velocity. This paper summarize all important steps during coil gun design, such as physical laws of the coil gun, preliminary calculations, the testing device and final product. The electromagnetic FEA model of the capacitor-driven inductance coil gun was constructed...

Design and Clamping Force Analysis of Vacuum Fixture to Machine Aerospace Components

Machining of thin-walled (aluminium alloy) aerospace structures is a critical process due to the high warpage. Current practices in the fixture design and the choice of cutting parameters rely solely on conservative guidelines and the designer’s experience. This paper presents evaluation of clamping force to fix the work piecein aVacuum fixture using Vacuum pump. The ISCARonline calculator is u...

Design of a Force-Free Inductive Storage Coil

Force-free coils have been considered for various applications as energy storage devices. A novel energy storage system consisting of both toroidal and poloidal coils has been developed. In this system, the Lorentz forces on the two coils are in opposition and can be made to cancel by having the proper ratio of ampere-turns in the two coils. A general discussion of force-free coil design is giv...
