Product Features

High thrust iron core design

Iron core linear motor structure supports stronger force density for industrial direct drive motion.

Fast response and acceleration

Suitable for equipment that requires quick start-stop motion and high-speed positioning.

Precision positioning

Supports accurate linear motion for inspection, measurement, laser and semiconductor systems.

Low mechanical wear

Direct drive structure reduces contact transmission parts and helps improve long-term stability.

Suitable for linear motor stage systems

Can be used as a core drive component for high-precision linear motor stages.

Flexible integration

Stroke, encoder, driver and controller matching can be configured according to machine design.

How to Choose

  1. Choose MK Series when the application requires higher thrust and direct drive acceleration.
  2. Use MK Series when the project needs stronger thrust, acceleration and stable direct drive performance.
  3. Confirm continuous thrust, peak thrust, stroke, encoder feedback, cooling method and installation space before selection.
  4. For semiconductor, laser and inspection equipment, match the linear motor with a suitable guide rail, scale and controller.
  5. For module-based positioning, connect users to NK Linear Motor Stage or other complete linear motor module pages.

WJM Series Frequently Asked Questions

01

What’s the difference between a ball screw, belt, and rack & pinion...

Ball screw modules offer high precision and rigidity for accurate positioning. 

Belt modules are ideal for high-speed, long-travel motion. 

Rack & pinion modules handle heavy loads and extra-long strokes.

02

How do I select the right linear module?

Selection depends on load, travel distance, speed, installation direction, and precision requirements. Our engineers can assist with model selection if you share your application data.

03

Can the module be mounted vertically?

 Yes, but vertical installation requires a brake motor or mechanical lock to prevent gravity drop.

04

What is the repeat positioning accuracy?

Ball screw type: ±0.01 mm; Belt type: ±0.05 mm; Rack & pinion type: ±0.1 mm.

05

Do the modules require maintenance?

Yes. Apply grease every 500 operating hours or 3 months and keep the guideways clean.

06

Which motor brands are compatible?

 Compatible with Delta, Mitsubishi, Panasonic,Yaskawa, Inovance, and most standard servo motors.

07

Can you provide custom stroke or dust-proof options?

Yes. Customized stroke lengths, dust covers, and mounting interfaces are available upon request.

08

What is a clean room belt driven linear actuator?

A clean room belt driven linear actuator is a linear motion module that uses a timing belt and linear guide structure to move a carriage along a straight axis. The MTG Series is designed for clean room and precision automation applications requiring high speed, long stroke, low noise and stable operation.

09

What is the MK Series iron core linear motor used for?

10

What is the advantage of an iron core linear motor?

11

Can MK Series be used in a precision linear motion system?

12

How is a direct drive linear motor different from a screw actuator?
