  • Publication number: 20070296368
    Abstract: The present invention relates to an apparatus and method for generating digital electrical signals which are representative of the angular position and rotational velocity of a rotatable shaft or similar movable mechanical component in a servomechanism. In particular, the present invention utilizes oversampling techniques to create an accurate, flexible and responsive method for determining shaft position on a high speed motor. The present invention also includes methods for overcoming deadtime losses and velocity lag.

  • Publication number: 20070273359
    Abstract: A modular current sensing system for a servo control system that includes a magnetic core with an open center portion and a connection plate that includes at least three wire connectors, wherein the wire connectors are capable of connecting at least two wires electrically in series. The system also includes a plurality of wires, including a first wire with a first end and a second end, wherein the first end of the first wire is electrically connected to a first power source, and the second end of the first wire is connected to the connection plate at the first wire connector and wherein the first wire passes through the open portion defined by the magnetic core at least once. A first motor current flowing through the first wire induces a core current to flow in the magnetic core, causing the magnetic core to emit a magnetic field. A Hall effect sensor detects the magnetic field, produces an output current, and delivers the output current to a control device within a servo control system.

  • Publication number: 20070140054
    Abstract: A quick-disconnect mixer drive system includes a drive adapted to be mounted on a mixing tank. The drive includes an output shaft; a first quick-disconnect coupling component mounted on the output shaft; and a second quick-disconnect coupling component adapted to be mounted on a mixing shaft of an associated mixing tank. The second quick-disconnect coupling component being shaped to engage the first quick-disconnect coupling component to transmit both clockwise and counterclockwise torque from the output shaft to the mixing shaft and resist relative longitudinal movement between the first and second quick-disconnect coupling components.
