positioning drives manufacturer in India Rollring Industry specilizes in making traverse assemblies and spooling machines, coil winding machines, takeup stands ,rewinding lines in India.

The active part of the positioning element consists of a stack of ceramic disks separated by thin metallic electrodes. The maximum operating voltage is proportional to the thickness of the disks. Most high-voltage actuators consist of ceramic layers measuring 0.4 to 1 mm in thickness. In low-voltage stack actuators, the layers are from 25 to 100 µm in thickness and are cofired with the electrodes to form a monolithic unit.
