MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202647090963 A) filed by Tau Motors, Inc. on July 27, 2026, for Asynchronous Rotor Control For A Switch Bridge Of A Wound Field Rotor.
Inventors include Swint, Ethan Bagget; Eull, William Michael; Stevenson, Gregory Gordon; and Pennington Iii, Walter Wesley.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: Systems and methods are provided for controlling the application of current to stator and rotor windings of a motor. An electric machine includes a stator including stator windings. A stator controller is configured to control current through the stator winding to generate a wireless power signal. A rotor includes a rotor winding and a rotor circuit. The rotor circuit includes a switch bridge coupled to the rotor winding and a capacitor coupled across the switch bridge. The rotor winding receives the wireless power signal from a stator winding of the stator windings. A rotor controller determines a capacitor voltage, a reference current based on the capacitor voltage, and a rotor current through the rotor winding. The rotor controller controls the switch bridge of the rotor circuit to change a switching state based on the reference current and the rotor current.
