Latest Patents

One of his latest patents is titled "Limp home operational mode for an electric vehicle." This invention provides methods and apparatus for a limp home operational mode for an electric motor system. The method includes determining whether a resolver has failed. When the resolver has not failed, the operation of the electric motor system utilizes resolver signals. Conversely, when the resolver fails, the system operates using sensorless rotor position and rotor speed signals.

Another notable patent is "Permanent magnet AC motor systems and control algorithm restart methods." This patent outlines systems and methods for starting or restarting PMAC motor system sensorless control algorithms. The system includes a PMAC motor with a rotor, an inverter, and a controller. The controller is equipped with various logic components designed to estimate the rotor's position and speed based on current detected in each phase of the inverter. The start/restart method involves determining the need to start or restart the sensorless control algorithm and modifying the inverter voltage accordingly.
