Overview
The ServoTube Module with fully integrated bearing
rail and position encoder offers unprecedented value in
high performance applications. The ServoTube Module
is a cost effective alternative to ballscrew and belt drive
systems where high speed and exibility are required.
absolute accuracy, from a non-contact, integral position
sensor. The standard ServoTube position encoder
output is an industry standard 1V pk-pk sin/cos signal.
For applications requiring higher levels of accuracy, the
ServoTube Module is available with a fully integrated
optical position encoder giving a resolution of up to 1
micron.
The non-contact nature of the direct linear drive results
in life expectancy far above that for typical belt drive
and ballscrew systems, with the added advantage of no
deterioration in accuracy or repeatability over the entire
life of the product.
The ServoTube Module is an ideal OEM solution for
easy integration into pick-and-place gantry and general
purpose material handling machines. The load is
mounted directly to the forcer giving a very stable base.
Servotube Modules can be easily integrated with each
other or with other ServoTube products to create multi-
axis systems with minimal design effort.
The ServoTube has superior thermal efciency, radiating
heat uniformly. High duty cycles are possible without
the need for forced-air or water cooling.
Servotube is complemented by a range of matched,
self tuning servo-ampliers and indexers complete
with plug and play cabling. Ampliers interface easily
to PLCs and feature CANopen network connectivity for
distributed control applications.
