Miniature Linear Stepper Motor 20mm 1KG Thrust M3 Lead Screw For D Printer, Industrial Precise Control,etc.

SM20-55L-T 20mm 1KG thrust M3 lead screw brass slider linear stepper motor

This is a 20mm diameter permanent magnet stepper motor attached with a bracket+lead screw +slider.

There are double linear bearings, and they can provide strong support to the slider, and make sure slider can move fluently when the load goes up.

Lead screw is regular M3 screw, pitch is 0.5mm, and the motor step angle is 18°/step, thus it takes 20 steps to rotate one turn.

Motor’s step length (resolution) is 0.025/step, please make sure that motor’s resolution is about meeting your precision requirement.

About linear stepper motor with slider:

Our slider motor is a full set of assembly including motor + lead screw + bracket + slider.

Motor’s step angle is generally 18°/step, which means 20 steps for each turn.

When motor rotates one turn, slider moves one lead.

For single start lead screws: pitch =lead.

So the step length is (step length means linear movement slider travels, when the stepper motor take exactly one step):

Lead screw lead/steps of each rotation

For example if lead screw is M2*0.4P (0.4mm pitch regular M2 lead screw), step angle of the motor is 18°, step length of this motor is 0.4mm/20=0.02mm/step.

Also, lead screw length is customizable, and we also need to adjust bracket’s design, if you customize lead screw length.

Application of stepper motors:

Stepper motors are used for precise control, widely used on medical equipment, 3D printer, industrial precise control, automation equipment, etc.

Stepper motors can be used in any mechanisms requirement precise conrtol and rotational/linear movement.

Advantage of stepper motors:

Stepper motor can reach precise control even without close-loop encoders / without feed back system, also they do not have electrical brushed. Thus there is no electromagnetic interference and electrical sparks issues. In some cases, they can replace DC brushed motors/ brushless motors.

Stepper motors are easy to control with drivers, and this feature establish its important position in the field of precise control.

1. Precise control achievable, programmable

2. Without electromagnetic interference & electrical sparks

3. Small size

4. Reasonable price

5. Low noise

6. Long service life
