Patent number: 11949289Abstract: A stator defines multiple stator poles with associated electrical windings. A rotor includes multiple rotor poles. The rotor is movable with respect to the stator and defines, together with the stator, a nominal gap between the stator poles and the rotor poles. The rotor poles includes a magnetically permeable pole material. The rotor also includes a series of frequency programmable flux channels (FPFCs). Each FPFC includes a conductive loop surrounding an associated rotor pole. The stator and the rotor are arranged such that the electrical windings in the stator induce an excitement current within at least one of the FPFCs during start-up.Type: GrantFiled: December 16, 2022Date of Patent: April 2, 2024Assignee: TAU MOTORS, INC.Inventors: Walter Wesley Pennington, III, Matthew J Rubin, Gregory Gordon Stevenson, Michael Parker Owen

Patent number: 11936255Abstract: An electric machine includes a stator and a rotor energizable by magnetic fields produced by the stator when receiving a stator current to produce relative motion between the rotor and the stator. A controller is configured to send the stator current through the stator at a current angle measured from the closest one of a pole of the rotor, determine a desired operational output of the electric machine, and determine a desired rotor motion corresponding to the desired operational output of the electric machine. The controller is further configured to calculate a vector control modulation applied to the stator that elicits the desired rotor motion, and adjust the current angle of the stator current based on the vector control modulation to cause the rotor to perform the desired rotor motion and achieve the desired operational output of the electric machine.Type: GrantFiled: June 9, 2023Date of Patent: March 19, 2024Assignee: Tau Motors, Inc.Inventors: Walter Wesley Pennington, III, Matthew J.

Publication number: 20230396111Abstract: An electric machine having a thermal management system includes a stator having a stator core, and a rotor having a rotor core that is moveable relative to the stator. At least one of the stator and the rotor include one or more windings. One or more coolant cans encapsulate one or more of the windings disposed on the at least one of the stator and the rotor in an interior compartment of the coolant can. The interior compartment of the coolant can defines a coolant flow passage through the one or more windings. The coolant can includes a coolant inlet and a coolant outlet in fluid connection with the interior compartment of the coolant can. The interior compartment of the one or more coolant cans are fluidically isolated from the stator core and the rotor core.Type: ApplicationFiled: October 27, 2021Publication date: December 7, 2023Inventors: Walter Wesley Pennington, III, Ethan Bagget Swint, Gregory Gordon Stevenson, Michael Parker Owen, Matthew Joseph Reeve, Matthew J.
