An analysis of the series generator — Shunt motor oscillator

IN THE COURSE of a University “Open House” exhibition at the University of Michigan, a self-excited series generator — shunt motor oscillator was demonstrated. This inspired some of the students to search the literature for a theoretical discussion of the rotating machine oscillator. When their search proved fruitless, this brief essay was prepared and some quantitative tests of the theory presented were made. These tests are submitted for what value they may have for other teachers and anyone else who might be interested in the subject of machinery system analysis.
