ST Motor

Category:

The ST Series piezoelectric motor is the smallest motor of its kind. The ST provides high resolution motion control for linear or rotary devices in a fraction of the space of traditional mechanisms. The ST is ideal for small stepping as well as continuous travel, with the ability to make step increments in the tens of nanometers and the ability to operate at speeds up to 250mm/sec.
