NEMA 8 20mm Hybrid Stepper Motor 1.8 Step Angle With Run Through Lead Screw Shaft

High precision 20mm NEMA 8 run through lead screw shaft hybrid stepper motor with manual nut

Description:

This is a 20mm diameter hybrid stepper motor with a run-through lead screw shaft.

There is a manual nut (brass nut) at the bottom, and users can rotate the motor manually with hand, when the power is off.

Lead screw is 3.5mm diameter, 0.3mm pitch, and step angle is 0.3/200=0.0015mm/step (It takes 200 steps to rotate one turn for 1.8 degree step angle hybrid stepper motors)

Please feel free to contact us, and we are able to customize shaft/motor parameter if needed.

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
