  • Motor control system, controller, and method
    Patent number: 11387763
    Abstract: A method of controlling an electric motor includes determining a PWM control signal, analyzing the PWM control signal to determine if components of the PWM signal are within a threshold amount of each other, applying duty-cycle blanking to the PWM control signal, if the components of the PWM control signal are within the threshold amount of each other, to generate an adjusted PWM control signal, and controlling the electric motor with the adjusted the PWM signal to limit parasitic effects.
    Type: Grant
    Filed: October 31, 2017
    Date of Patent: July 12, 2022
    Assignee: Eaton Intelligent Power Limited
    Inventors: Sayeed A. Mir, John D. Neely, Stanley L. Seely, John M. White

  • Controllable torque transfer differential mechanism using magnetorheological fluid
    Patent number: 6454674
    Abstract: A method of controlling torque transfer from a torque input source to an outlet source in which an electronically controllable magnetorheological fluid-based torque limiting device is coupled to either a differential pinion gear, a side gear, both the differential pinion gear and side gear, or both side gears of a differential assembly. By introducing current through electronically controllable magnetorheological fluid-based torque-limiting device during a turning or spin-out condition, and thereby increasing the viscosity of the magnetorheological fluid within the torque limiting device, the amount of torque that is transferred to the output source through the differential assembly can be controlled.
