Linear Stepper Motor

—— 15 Years Experience of Stepper Motor & Brushless Dc Motor Manufacturing ——

A linear stepper motor is an electromechanical device that directly produces linear motion without intermediate mechanical transmissions like screws or belts. It combines the discrete motion steps of a stepper motor with a planar or tubular mechanical layout to create precise linear displacement.

Linear stepper motors are typically composed of: 

• Forcer (moving part) 
• Platen (stationary part) 
• Magnetic or electromagnetic winding structures 

By energizing the motor windings in specific sequences, the forcer moves incrementally along the platen, achieving high levels of precision and repeatability.

LeanMotor's linear stepper motors come in several types, each suited to specific applications: 

• External Linear Stepper Motor (T-type and ball screw) 

This type features an external threaded shaft. When the motor rotates, the shaft translates the rotary motion into linear motion. It is commonly used in applications requiring high-speed and long-stroke movements. 

• Captive Linear Stepper Motor 

Captive motors include an integrated shaft and nut assembly that restricts the motion to linear travel. These motors are ideal for applications requiring guided motion. 

• Non-Captive Linear Stepper Motor 

Non-captive motors allow the shaft to move freely while the nut remains stationary. They are versatile and used in applications where custom mounting is required.
