An apparatus or actuator system having a motor, a housing and a thrust rod or thrust tube, where the actuator is configured to convert rotational motion of the motor into axial motion of the thrust tube for axial motion of a tool coupling therewith. A guide assembly is coupled to the actuator housing, extending along an axis thereof. The guide assembly comprises a guide shaft and a coupling between the guide shaft and the thrust tube, and is configured to provide positional stability for the tool coupling when positioned along the actuator axis by motion of the thrust tube.

Integrated guide linear actuator system

A compact, axially aligned brushless servo motor actuation unit configured to manipulate a choke valve to control the pressure within a borehole during managed pressure drilling. The actuation unit including a brushless servo, a gear reduction assembly and a planetary roller actuator substantially aligned along a longitudinal axis and housed within a tubular housing, the gear reduction assembly defining a hollow core sized to enable a portion of a roller screw of the planetary roller actuator to pass therethrough for the purpose of reducing the overall length of the actuation unit along the longitudinal axis.

Actuator for choke valve

An apparatus comprises an actuator having a motor, a housing and a thrust rod, where the actuator is configured to convert rotational motion of the motor into axial motion of the thrust rod. A movable holder is coupled to the thrust rod, and configured for axial motion of a tool coupling therewith. A bearing assembly is coupled to the actuator, extending along an axis thereof. The bearing assembly is configured to engage with the bearing to provide positional stability for the movable holder and tool coupling, when positioned along the actuator axis by motion of the thrust rod.

High stiffness thrust component for linear actuator

An assembly comprises a housing, a motor within the housing, and a thrust tube with an anti-rotation mechanism. The motor comprises a hollow rotor. An externally threaded screw shaft is coupled to the hollow rotor for rotation therewith. An internally threaded nut is coupled to the externally threaded screw shaft, wherein rotation of the screw shaft causes the nut to move axially. The thrust tube is operably connected with the nut, and the anti-rotation mechanism is attached to the thrust tube to substantially prevent rotation relative the housing.

Linear actuator with anti-rotation mechanism

A linear actuator and housing assembly may be used to increase motor performance and dissipate excess thermal energy. One embodiment relates to an actuator housing and an electric motor coupled to the actuator housing, where the electric motor is disposed within the actuator housing such that there is a close proximity between the actuator housing and the motor. A linear actuator assembly may be operably coupled to the electric motor, where the linear actuator assembly is disposed within the actuator housing and a thermally conductive material is disposed between the actuator housing and motor.
