Stepper motor linear actuators – Q&As

A stepper motor linear actuator is a compact device that integrates a motor, lead screw, and nut into a single unit. 

The stepper motor's rotational motion is converted into linear motion through the interaction of all these components.

Linear actuators with a stepper motor are perfect for applications that demand very high positioning accuracy along an axis. They provide a powerful, space-saving solution and can be efficiently integrated into custom applications.

There are three types, or designs, of linear actuators with stepper motor: non-captive actuators, captive actuators and external actuators.
 

Stepper motor linear actuators are commonly used in medical technology, laboratory automation, optical technology, and semiconductor manufacturing. They enable precise, repeatable micro-movements in pipetting devices, support equipment in ophthalmology, and ensure reliable dosing in infusion pumps, among other applications.

Non-captive linear actuator – without linear guide
A non-captive actuator (LA) offers maximum flexibility. With a variety of screws available in different leads, diameters, and lengths, it's easy to find the best solution for every specific requirement.
 

Captive linear actuator – with linear guide
Captive linear actuators (LGA) feature an integrated anti-rotation device, allowing the lead screw to extend and retract according to the direction of rotation. This actuator is ready for immediate use and optimal for short strokes.
 

External linear actuator – external linear
An external linear actuator (LSA) can be combined with both standard nuts and anti-backlash thread nuts, ensuring high repeatability even with load changes.
 

Selecting the right lead screw is crucial for the actuator's performance, along with choosing the correct motor size.

The diameter of the lead screw should match the size of the hollow shaft or the NEMA size of the motor. The screw lead determines how rotary motion is converted into linear motion. 

A higher lead allows for higher speeds, lower forces, and longer service life, while a lower lead generates higher forces and provides stronger self-locking, helping the actuator maintain its position even when power is off.

Webinar: Linear Actuators – Types and Function

What are the different types of linear actuators and how do they differ? How do I find the right lead screw and why is the thread lead so important? The Nanotec experts will answer these and all other questions in our 20 minute webinar. 

We provide you with equations for converting torque into thrust and also discuss these topics in detail: 

  • Types of threaded nuts
  • Axial backlash
  • Criteria for self-locking
  • Extending the service life

When used with a closed-loop controller, the linear actuators from Nanotec can be controlled via fieldbus, clock & direction or analog/digital inputs. The feed force can also be controlled when the linear actuators are combined with an encoder.
