20mm diameter linear actuator motor high accuracy with POM plastic
slider
This is a 20mm diameter linear stepper motor with M3*0.5P lead
screw. Lead screw pitch is 0.5mm.
Travel distance(stroke) is about 66mm, and if customers what
longer/shorter travel distance, we also have other lead screw
length options.
The thrust of this motor is more than 1KG (10N), if customers do
not need this much of thrust, and need smaller size, we also have
15mm motor with the same design as well, and its thrust is more
than 500g (5N).
The slider is plastic(POM), we also have brass slider option, and
it has double linear bearings with it. The cost of brass slider is
higher than plastic slider design.

or you have any questions about this motor.

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
