Tr3.5 trapezoidal lead screw 20mm NEMA 8 hybrid stepper motor with optical encoder

Description:

This is a 20mm hybrid stepper motor (NEMA 8) attached with trapezoidal screw.

Trapezoidal screw is Tr3.5x4, lead screw pitch is 1mm, so lead is 4mm.

Also this motor has an optical encoder at it bottom.

We have different resolution for you to choose.

Standard resolution is 1000 CPR (Changes Per Resolution)

If customers do not require encoder, we can remove encoder as well.

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
