  • Actuator with motor and feedback driven by a common power supply
    Patent number: 5389864
    Abstract: An actuator system has a motor and an output shaft connected to a potentiometer that provides shaft position information. The motor and potentiometer are electrically connected to a common power supply. A microcomputer controls the application of power to the motor and potentiometer so that feedback signals from the potentiometer, indicative of shaft position, can be read when desired without moving the shaft. The motor is prevented from moving either by setting both motor terminals high during a read, or by applying power pulses during a read which are too short in duration to allow the motor to start moving.
