External Stepper Motor Actuators
Our External Stepper Motor Actuators offer a highly configurable solution for linear motion systems where the motor and nut/screw assembly are separated which enables designers to place the motor remotely or integrate it into an existing architecture while still leveraging a precision lead-screw drive. These actuators provide designers with flexibility, performance, and precision in one compact system.
Engineered for Your Application
- External-motor configuration means the stepper motor drives a lead screw that moves the nut (or the screw translates) while the motor remains mounted independently. This is ideal for space-constrained or modular designs.
- Available in multiple NEMA motor sizes (e.g., NEMA 14, 23, 34) with a range of screw diameters, leads, stroke lengths, and nut options which enables you to tailor performance to your application requirements.
- Designed for repeatable, precise motion, Helix supports your specification with application engineering to select the correct lead screw geometry, nut type, motor stack, and assembly layout.
Applications & Industry Fit
External stepper motor actuators are especially useful when your machine or equipment requires a separate motor mounting, disconnected powertrain, or unique integration path that is common in automation systems, instrumentation, medical devices, robotics, and aerospace where design flexibility and precision matter most.
Why Choose Helix Non-Captive Stepper Motor Actuators?
- U.S. manufacturing in Beachwood, Ohio, with full traceability, quality control, and engineering support.
- Broad configuration options like motor size, screw lead, stroke, nut type. You don’t compromise system design due to component limitations.
- Application-engineering support from concept to production, ensuring your actuator matches your system’s operational, duty-cycle, and environmental requirements.
- Part of a full motion-component ecosystem because Helix also provides screws, nuts, actuators and custom services. This way you benefit from integrated design thinking and simplified supply chain.
Helix Linear Technologies isn’t just providing components. You’re gaining a motion-system partner. When your design demands a flexible, precision linear actuator with a remote or external motor configuration, choose our External Stepper Motor Actuators.
