High thrust 15mm SM15-80L-T M3 lead screw brass slider PM linear stepper motor

SM15-80-T is a 15mm diameter stepper motor attached with a M3 lead screw, bracket and brass slider.

Lead screw is regular M3 screw with 0.5mm pitch.

About the slider, it’s brass slider made from CNC.(We also have plastic slider option, which is cheaper, and customer can choose plastic slider if they want to save cost)

This biggest advantage of brass slider is that it has two linear bearing holding it and these two bearings provide strong support to the slider, make sure the slider moves smoothly even when load is high.

Thus brass slider have better stability, and the price is higher for a good reason.

If customers think the stroke(travel distance) is too long, we also have other stroke for options.

(Stroke/travel distance is determined by lead screw length)

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
