摘要： A rotary electrical actuator for mounting to a support surface in industrial applications having integral electronics that are isolated by vibration isolators from vibrations. The rotary actuator comprises a stator housing supporting a lamination stack and coils. The actuator housing has a mounting structure for mounting to the support surface (such as the mounting surface of an engine or a turbine for example) for support thereby. A rotor is carried for rotation in the stator housing. The actuator further comprises an electronics housing containing the electronics that control output of the electrical actuator. Vibration isolators supported by the stator housing in turn support the electronics housing, whereby vibrations received at mounting structure and traveling through the stator housing are dampened prior to traveling to the electronics housing. A number of embodiments are disclosed utilizing a tie rod assembly concept for the vibration isolators.

摘要： A electrical solenoid suitable for fluid controls applications with an elastomeric retaining device of an elastomeric material arranged between the housing and the lamination stack. The elastomeric retaining device eliminates the need for potting compound and the associated steps of filling the housing with potting and curing the potting compound. The solenoid has a wire coil wound about the lamination stack in which the wire coil has an electrical connection extending through the housing for electrical communication with an external electrical control. The end of the lamination stack projects out of the housing slightly after manufacturing and assembly. When the solenoid is mounted, the elastomeric retaining device biases the lamination stack against the mounting surface. The wire coil is pre-assembled in a wire coil assembly comprising a bobbin, a wire coil wound about the bobbin and a plastic overmold encapsulating the wire coil and bonded to the bobbin.

摘要： An apparatus for sensing rotary position that is particularly suited for electrical rotary actuators. The sensing apparatus comprises a magnet and a hall effect detector, both of which are arranged along the axis of rotation. The hall effect detector senses the angle of the return loop of magnetic flux lines from the north to the south pole of the magnet. When the magnet rotates relative to the hall effect detector, the angle of the magnetic flux lines changes which is detected by the hall effect detector. The arrangement of the magnet and the hall effect detector on the shaft axis of a rotary actuator avoids the magnetic flux line interference that is naturally produced by electrical actuators.
