Electric Motor Secrets Part 1 & 2 by Peter Lindemann, DSc shows patents, diagrams, schematics, working models, and table-top demonstrations with meters, so you can understand all of the principles he discusses. Electric Motor Secrets was and still is the most comprehensive tutorial on electric motor history and function available on the Internet. It also opens the eyes of the student to possibilities not taught in school.
In Electric Motor Secrets Part 2, Peter covers the history of the “self-running” power system known as the “Lockridge Device”, as well as its construction and theory of operation. In it, he looks deeply into the torque characteristics of electric motors operated on capacitor discharges and how this can radically reduce their energy losses caused by “back EMF.”
