Stepper motor Linear actuators technology
Stepper motor Linear actuators advantages:
Small to medium load ratings
Very high travelling speeds, thanks to over-square pitches (p ≤ 6 × d)
High efficiency (µ~0.5...0.8), thanks to high surface quality of the steel leadscrews
Weight optimization possible based on aluminium screws
High reliability and long service life with marginal need for maintenance

Linear actuators convert rotational motion in motors into linear or straight push/pull movements
Linear actuators are ideal for all types of applications where tilting, lifting, pulling or pushing with high force are required.
External Hybrid Stepper motor Actuators:
The lead screw turns with the rotor, moving a nut back and forth linearly. An external guide is necessary to prevent rotation of the nut. In the case of external linear actuators, the lead screw is permanently attached to the motor shaft and turns with the shaft when the motor is energized. If an external threaded nut – in standardized or anti-backlash version – is mounted on the lead screw and secured against rotating by an external guide, the threaded nut moves along the lead screw.
