External drive PM linear stepper motor featuring direct-drive precision. High torque-to-size ratio and customizable traveling nuts for light industrial automation, robotics, and medical devices.

Designed for flexible linear movement, our external drive PM linear stepper motor pairs a permanent magnet stepper motor with an extended, precision-machined lead screw shaft. In this configuration, the screw is fixed to the rotor and rotates with the motor, driving an external nut back and forth along the shaft.

Equipped with optional wear-resistant plastic or bronze external nuts, this external linear actuator provides direct-drive precision, long service life, and reliable linear motion for light industrial and medical applications.

Key Features & Advantages

• Direct-Drive Integration: Eliminates shaft couplers to reduce mechanical backlash and dynamic axial runout.

• Customizable Nut Designs: Available with cylindrical nuts, flanged nuts, and spring-loaded anti-backlash nut assemblies.

• High Power Density: Compact permanent magnet design produces strong linear thrust in a space-saving construction.

• Low Maintenance: Self-lubricating nut options ensure smooth, clean operation without frequent re-lubrication.

Technical Specifications

Typical Applications

• Light-Duty Gantry Pick-and-Place Arms & Micro-Robotics

• Medical Reagent Mixing & Automated Fluid Control

• Optical Shutter Mechanisms & Camera Stage Positioning

High-efficiency non-captive PM linear stepper motor with through-shaft design. Flexible stroke length and compact profile for medical automation, HVAC, and robotics. Request a quote today.

The non-captive PM linear stepper motor utilizes an internal rotating nut embedded directly inside the motor rotor. The precision lead screw passes completely through the center of the motor shaft. When the screw is fixed to an external load that prevents rotation, the screw translates axially through the motor body.

This through-shaft permanent magnet linear actuator offers complete flexibility in travel stroke, as screw length is not limited by the motor housing size. It provides a compact, low-cost solution for versatile linear positioning across varied machinery footprints.

Key Features & Advantages

• Unlimited Travel Stroke: The screw passes through the motor body, enabling stroke lengths customized to your exact application needs.

• Streamlined Design: Eliminates bulky external couplings, motor mounts, and additional shaft support bearings.

• High Efficiency & Quiet Operation: Precision-molded internal nuts ensure smooth, quiet motion with low friction wear.

• Economical OEM Solution: Delivers excellent force-to-cost performance for high-volume automated manufacturing.

Technical Specifications

Typical Applications

• Automated Medical Laboratory Dispensers & Pipetting Stations

• HVAC Damper Actuators & Airflow Control Valves

• Automated Sorting Trays & Light-Duty Material Handling

Precision captive PM linear stepper motor with built-in anti-rotation mechanism. Compact, cost-effective linear actuator for medical pumps, valve control, and automated instruments.

Our captive PM linear stepper motor features an internal anti-rotation mechanism that prevents the lead screw from spinning. As the permanent magnet motor rotates, the lead screw extends and retracts directly from the front faceplate without requiring external anti-rotation guides or linear rails.

This self-contained, cost-effective permanent magnet linear actuator provides a plug-and-play solution for short-stroke precision positioning. Offering a high force-to-size ratio and low power consumption, it is engineered for compact OEM equipment requiring dependable linear motion.

Key Features & Advantages

• Built-in Anti-Rotation Mechanism: The screw shaft moves in a pure linear direction without rotating, saving mechanical space and installation time.

• Cost-Effective Precision: High force output in a lightweight, economical permanent magnet design ideal for volume OEM applications.

• Self-Locking Safety: Trapezoidal thread design provides inherent back-driving resistance to hold position when power is off.

• Compact Footprint: Modular canister sizes allow easy integration into portable and space-restricted devices.

Technical Specifications

Typical Applications

• Portable Medical Diagnostic Devices & Syringe Pumps

• Electronic Fluid Control Valves & Dosing Equipment

• Automated Office Equipment & Consumer Electronics Test Rigs
