Abstract: 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.

Abstract: An integrated motor linear actuator system includes one or more stator stages inside a housing. The stator stages have a winding and a stator core disposed about a common longitudinal axis, with a plurality of stator teeth configured to guide magnetic flux generated by the winding. A rotor is disposed along the longitudinal axis, within the stator stages, with a plurality of magnetic poles distributed circumferentially about the outer surface, adjacent the stator teeth, so that the stator stages are configured to drive the rotor into rotational motion about the longitudinal axis via the magnetic flux. A thrust tube and screw assembly are operationally coupled to the rotor, and configured to convert the rotational motion into linear motion of the thrust tube.

Abstract: An integrated power clamp motor system includes a housing with one or more stator stages coupled to the inner surface. Each of the stator stages has a winding and a stator core with a plurality of stator teeth circumferentially distributed about a longitudinal axis, at an inner diameter of the stator core. A rotor is disposed about the longitudinal axis, inside the stator core, with a plurality of magnetic poles circumferentially distributed along an outer surface, adjacent the stator teeth. A power clamp assembly is coupled to the rotor via one or more of a screw assembly, a thrust rod, and a transmission, and operational between first and second positions responsive to rotation of the rotor.
