Overview of NEMA 14, 17, and 23 linear actuators (with external and non-captive screws)

In this video, Lisa Eitel and Lee Teschler explain the differences between six linear actuators from Schneider Electric Motion USA in NEMA sizes 14, 17, and 23. These linear actuators incorporate stepper motors to deliver long life and high accuracy and repeatability. The compact IP20 motors are 1.8° step-angle motors pre-integrated with leadscrew assemblies to satisfy an array of linear-motion applications.
With variations having an external shaft, the rotating screw is integral to the motor’s rotor and a mating nut travels axially along the threaded screw’s shaft. In contrast, versions with a non-captive leadscrew have the threaded shaft pierce through the motor to move axially with the motor rotor’s output rotation.
No matter the variation, the precision rolled leadscrews are quiet - especially when paired with a self-lubricating nut. Because the leadscrews are made of premium non-magnetic stainless steel, they’re also corrosion resistant. It’s also possible to specify the linear actuator’s screws with a Teflon coating.
