A linear actuator is a device that develops a force and a motion through a straight line. A stepper motor-based linear actuator uses a stepping motor as the source of rotary power. Inside the rotor, there’s a threaded precision nut instead of a shaft. The shaft is replaced by a lead-screw. As the rotor turns (as in a conventional stepper motor), linear motion is achieved directly through the nut and threaded screw. It makes sense to accomplish the rotary to linear conversion directly inside the motor, as this approach greatly simplifies the design of rotary to linear applications. This allows high resolution and accuracy ideal for use in applications where precision motion is required.

Generally, the application stroke of non-captive shaft stepper motor linear actuator is usually 30-200mm. Compared with external shaft motor, the advantage of non-captive shaft linear actuator is to allow greater installation coaxality error. If the lead screw and nut of linear module and the lead rail parallelism are not good, it will cause the system problem. Although the nut allows a certain clearance diametral, it is not enough for the whole module. The nut clearance diametral of the non-captive shaft stepper linear actuator allows the tilting degree of lead screw within 1 degrees and can tolerate more systematic error.

The characteristics non-captive shaft stepper linear actuator is to use the motor as the sliding part to connect the motor with lead rail slider with both ends of the guide screw fixed. One advantage of this type of motor is that the lead screw does not rotate, so there is no limit of the critical speed. Another advantage is that multiple motors can be installed on the same lead screw, and the motor cannot "pass" each other, but its motion is independent of each other.
