Tesla Single Circuit Alternating Motor

In a patent issued to Mr. Nikola Tesla on January 2, entitled, "Electrical Transmission of Power, No. 311,915, originally filed May 15, 1888," is described a method of operating motors from a two-wire alternating circuit. The method employed is set forth in the two claims of the patent as follows:

1. The method of operating electromagnetic motors having independent energizing circuits, as herein described, which consists in passing an alternating current through one of the energizing circuits and inducing by such current the current in the other energizing circuit of the motor, as set forth.

2. The method of operating electromagnetic motors having independent energizing circuits, as herein described, which consists in developing an alternating current in one of said energizing circuits, and inducing thereby currents in the other energizing circuit or circuits, as herein set forth.
