Page 6 of catalogue Rail guide tables of SKF Linearsysteme GmbH

Tables with a linear motor drive: These are equipped with brushless AC Motors and work as follows: • The secondary part in the lower part of the table takes the form of a magnetic rail. • The primary part is located in the travelling upper part of the table and takes the form of a coil system. • Two or three-phase AC Synchronous motors with electronic commutation. • Linear measuring system, integrated in the table as standard.

Customer benefits: • High dynamics and stiffness in a closed loop system. • Good synchronous characteristics. • High acceleration capacity. • High travel speeds, even with large strokes. • Friction and wear free drive. See table 3 for further technical details.
