You can do your location control applications with easy to use NEMA series bipolar step motors, set motor revolution with step motor driver cards.

You can provide the linear movement which you need in many projects with the 28 cm screw shaft on step motor.

It can be used in desktop CNCs and 3D printers easily. There are 4 3mm stabilizing holes on hub on screw shaft. On each step of step motor there is a 0.04mm vertical forward movement. On one full tour there is a 200mm forwarding. This sensitivity can be even lower in half or quarter step operations. Therefore with 1/32 micro step drive, up to 1.25 µm resolution can be achived. Under normal circumstances max. 30 cm/s speed can be reached.
