Further excursions in computer aided magnetic devices

Abstract

An understanding of the interchange between electrical and magnetic energy in electromechanical devices and systems is essential to the description of how solenoids (singly excited) and other (doubly-excited) electromechanical devices work. By utilizing conservation of energy principles, one can calculate the forces and the resultant motion for doubly-excited systems. This paper details the principle of co-energy as it applies to nonlinear systems. The program and results for actual devices are discussed.
