  • Backlash measurement system for an electromechanical actuator
    Patent number: 11761851
    Abstract: A drive system includes a motor having a rotatable output shaft that is operably coupled to a lead screw by a transmission that converts rotary output of the motor into linear translation of the lead screw.
