Armature for Critical Infrastructures

2006 IEEE International Conference on Systems, Man and Cybernetics, 2006
Critical infrastructures have elevated requirements on security and availability. However, where security and availability are issues, security assurance evaluation becomes crucial. Evaluating security assurance is a non-trivial problem. In this paper, we discuss several security assurance aspects and the role of modeling in this context.

Experimental study of armature melt wear in solid armature railgun

2014 17th International Symposium on Electromagnetic Launch Technology, 2014
Transition is an important issue in rail electromagnetic launches which limits the performance of electromagnetic launch systems. In the launch progress, wear on contact surface of armature significantly affects the morphology of contact surface and armature structure.

Double Armature a. C. Generator

IEEE Power Engineering Review, 1989
The possibility of constructing an electrical machine which rotates at twice the speed of the rotating field is described. After a qualitative analysis of the electrical phenomena involved, a description is given of a complete mathematical model which is used to analyze both steady-state and transient behavior.

Effects of Armature Characteristics on Armature-Rail Contact Performance

IEEE Transactions on Plasma Science, 2017
Armature-rail contact performance determines contact resistance between the armature and rail in electromagnetic launch, and the contact resistance directly affects the efficiency of the launch system. Besides, poor contact performance between the armature and rail will results in erosion, gouging, and other issues in launch.
