  • Direct drive servovalve device with redundant position sensing and methods for making the same
    Patent number: 7882852
    Abstract: A direct drive servovalve device includes (i) a servovalve motor having a stator and a rotor assembly configured to rotate relative to the stator, (ii) a valve member coupled to the rotor assembly, and (iii) a sensor assembly. The sensor assembly includes an interface configured to couple to a controller that controls the servovalve motor, a set of programmable Hall sensors coupled to the interface, and a support. The support (e.g., a ring-shaped collar or sleeve) supports the set of Hall sensors at an installation location which is (i) adjacent to the rotor assembly and (ii) fixed relative to the stator. The set of programmable Hall sensors is configured to provide a set of position signals to the controller through the interface. The set of position signals identifies a rotational position of the rotor assembly relative to the stator.

  • Motor/spool interface for direct drive servovalve
    Patent number: 6000678
    Abstract: A direct drive servo valve including a motor having a shaft terminating in an engagement member. The engagement member is received within an opening defined by an engineering plastic material which is coupled to a valve member. The valve member is caused to reciprocate by rotation of the shaft of the motor to control the flow of fluid underpressure from a source thereof to output ports which are in turned coupled to a load.
