SERVOTUBE LINEAR MOTORS
The Servotube Linear Motor is physically like a conventional 3-phase brushless linear motor - with one difference: The magnets are potted into a round shaft, which runs thru the center of the winding assembly. This leads to a symmetrical design, which results in a balancing of the magnetical attraction forces. Another advantage of this mechanical arrangement is the enclosed housing so that IP67 is possible.
The biggest advantage of the Servotube Motor however is the integrated linear encoder: The magnets of the Servotube provide the scale for the precise analog hall sensors and the given position information is processed to the standard 1Vp-p industrial sine / cosine signal. Most of the modern servo amplifiers are able to read this position feedback. This makes the Servotube linear motors to easy to use and very cost effective linear motors, which achieve a repeatability of up to +/-8µm (depending on size).
Mechanically the Servotube linear motors are used with conventional linear guiding systems. The comparably large airgap of about 1mm around the shaft allows an easy integration.

brand new: Servotube Linear Actuator in stainless steel for wash down applications
Copley comes up with a brand new design of the servotube actuators in stainless steel, ideally suited for applications ins pharmaceutical and food industry; to meet the typical requirements the stainless steel actuator comes with a very smooth surface and meets protection class IP69K. To be compatible to other servo drives the new actuators have been designed in 600V technology and the encoder is a digital incremental encoder plus hall effects. The absolute accuracy is +/-400 µm and the repeatability is 25µm.
In a first step the ServoTube Hygienic comes in two version – the models XHB3804 and XHB3810 offer maximum forces of 744 and 1860N. The optional watercooling allows a increase of the continuous force of up to 70% for applications with high duty cycle or for operation at high ambient temperatures.
