Product 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.

Design drawing
Customisable
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.
Areas of 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.
