  • Motor control
    Patent number: 9909601
    Abstract: A motor control system includes a piston chamber and a piston assembly disposed within the piston chamber to move therein between first and second positions. A magnet is coupled to the piston assembly to move therewith and a sensor is axially mounted with respect to the piston assembly to generate a continuous output signal corresponding to a position of the magnet relative to the sensor. The motor control system also includes a controller for processing the output signal from the sensor to monitor continuously the position of the piston assembly within the piston chamber and for actuating the piston assembly to move in an upstroke toward the first position and in a downstroke toward the second position.
    Type: Grant
