Technical Information

Product Details

Ultra-compact NEMA 11 linear lead screw servo motor. High-speed closed-loop positioning and precision lead screw integration for micro medical devices and robotics.

 

The NEMA 11 linear lead screw servo motor is an ultra-compact, closed-loop linear motion solution designed for high-precision applications where space is extremely limited. Combining a 28mm high-density servo motor with an integrated precision ACME or ball lead screw, this micro linear actuator provides high positioning resolution, real-time position feedback, and zero step loss.

Equipped with an integrated high-resolution optical or magnetic encoder, this compact linear servo actuator delivers smooth, whisper-quiet operation and precise torque control, making it ideal for micro-fluidics, semiconductor alignment, and miniaturized medical devices.

Key Features & Advantages

  • Ultra-Compact 28mm Footprint: Delivers precise closed-loop linear motion within a miniaturized NEMA 11 motor frame.

  • Closed-Loop Precision: Integrated high-resolution encoder prevents stall conditions and eliminates lost steps.

  • Direct-Drive Efficiency: Eliminates flexible couplings to maximize torsional stiffness and minimize backlash.

  • High-Speed Positioning: Supports higher speed profiles and smoother acceleration curves compared to standard open-loop stepper systems.
