20mm Diameter High Precision Linear Stepper Motor With M3 Lead Screw Brass Slider 1.2KG Thrust
Description
This is a 20mm diameter permanent magnet stepper motor with brass
slider.
The brass slider is made from CNC and it has double linear bearing
to provide strong support.
The thrust of the slider is 1~1.2 KG(10~12N), and the thrust is
related to motor’s lead screw’s pitch, driving voltage and driving
frequency.
A M3*0.5mm pitch lead screw is used on this motor.
When driving voltage gets higher, and driving frequency gets lower,
slider’s torque will be bigger.
Motor’s stroke (travel distance) is 35 mm, we also have 21mm and
63mm stroke for options, if customers want shorter size.
The motor’s connector is P1.25mm pitch, 4 pins connector. We can
customize and change it into other connector type if customers
require other pitch connectors.

About linear stepper motors
A linear stepper motor has lead screw to convert the rotation
movement into linear movement. Stepper motors with lead screw can
be considered as linear stepper motor.
A slider linear stepper motor contains a bracket, slider, and
supporting rods are added, based on the external drive linear
motor’s design. Because supporting rods provide anti-rotation
mechanism for the slider, slider can only do linear movement.
The lead screw’s lead equals to its pitch, and when motor rotates
one turn slider moves exactly one pitch of distance.
For example, if motor’s step angle is 18°, it means it takes 20
steps to rotate one turn. If the lead screw is M3*0.5P, pitch is
0.5mm, slider moves 0.5mm for each revolution.
Motor's step length is 0.5/20=0.025mm. This means when the motor
takes one step, the linear movement of the screw/slider is 0.025mm.
For motors with the same diameter and torque, the longer step
length it has, fast linear speed it will have, but smaller thrust
will have at the same time.
Linear stepper motor type
Application
Motor’s speed is determined by driving frequency, and it has
nothing to do with load (unless it’s losing steps).
Due to high precision speed control of stepper motors, with a
driver controlled stepping you can achieve very precise positioning
and speed control. For this reason, stepper motors are the motor of
choice for many precision motion control applications.
For linear stepper motors, they are widely used in:
Medical device
Camera equipment
Valve control system
Test instrument
3D printing
CNC machine
and so on
Customization service
Motor’s design can be adjusted based on customer’s requirement
including:
Motor’s diameter: we have 6mm, 8mm, 10mm, 15mm and 20 mm diameter
motor
Coil resistance/ rated voltage: coil resistance is adjustable, and
with higher resistance, motor’s rated voltage is higher.
Bracket design/ lead screw length: if customer want the bracket to
be longer/short, with special design such as mounting holes, it’s
adjustable.
PCB + cables + connector: PCB’s design, cable length and connector
pitch are all adjustable, they can be replaced into FPC if
customers require.

FAQ
1.Are you a manufacturer?
Yes, we are a manufacture, and we produces mainly stepper motors.
2.Where is your factory location? Can we visit your factory?
Our factory is located in Changzhou, Jiangsu. Yes, you are very
welcome to visit us.
3.Can you provide free samples?
No, we don’t provide free samples. Customers won’t treat free
samples fairly.
4.Who pays for shipping cost? Can I use my shipping account?
Customers pay for shipping cost. We will quote you shipping cost.
If you think you have cheaper/more convenient shipping method, we
can use you shipping account.
5.What’s you MOQ? Can I order one motor?
We don’t have MOQ, and you can order only one piece sample.
But we recommend you to order a little bit more, just in case the
motor is damaged during your testing, and you can have a back-up.
6.We are developing a new project, do you provide customization
service? Can we sign a NDA contract?
We have over 20 years of experience in stepper motor industry.
We have developed many projects, we can provide full set
customization from design drawing to production.
We are confident we can give you few advice/suggestions for your
stepper motor project.
If you are worrying about confidential issues, yes, we can sign a
NDA contract.
7.Do you sell drivers? Do you produce them?
Yes, we do sell drivers. They are only suitable for temporary
sample test, not suitable for mass production.
We do not produce drivers, we only produce stepper motors
