Technical Information
Product Details
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.
