  • Stall thermal protection for force feedback actuator
    Patent number: 12227235
    Abstract: A method includes receiving motor velocity data, and, in response to a determination that the motor velocity data indicates that a velocity of a motor is below a threshold velocity: calculating a thermal metric corresponding to a phase imbalance of the motor; identifying at least one thermal mitigation parameter based on the thermal metric; generating at least one thermal management motor position command based on the at least one thermal mitigation parameter; and selectively controlling the motor according to the thermal management motor position command.
    Type: Grant
    Filed: June 17, 2022
    Date of Patent: February 18, 2025
    Assignee: Steering Solutions IP Holding Corporation
    Inventors: Thomas J Stutts, Michael A Eickholt, Steven J. Collier-Hallman, Julie A Kleinau, Prerit Pramod
  • Systems and methods for real time permanent magnet synchronous machine control
    Patent number: 12077143
    Abstract: A method includes calculating, for a motor, a voltage constraint and calculating, for the motor, a supply current constraint and a regenerative current constraint. The method also includes calculating, for the motor, a motor current constraint and determining, for the motor, a first operating torque based on the voltage constraint, the supply current constraint, and the motor current constraint. The method also includes at least one of selectively controlling the motor based on the first operating torque and generating information associated with the first operating torque.
