Hollow-shaft motors

Nanotec offers stepper motors with hollow shaft in four sizes. The hollow shaft can be used to pass cables or conduct laser beams through it or to hold other machine elements, such as axes or shafts.

4 sizes
Weight and space savings
Second shaft end for mounting an encoder (SCA series)
1.8° step angle

An extensive range of customized shaft and cable versions can be found under Individual Solutions.
