ServoTube is the first three-phase linear motor designed specifically for use as an actuator. Combining the speed and rugged operation of pneumatics, the controllability of a ball screw and the inherent reliability of direct drive linear motors, ServoTube is a low-cost, powerful industrial pusher/puller. It is suited to stacking, cutting, pressing, coating, filling, and pick and place applications, particularly in the food and packaging industries.

The simple two-part design makes the ServoTube very reliable, with a service life up to 10 times that of a ball screw. Using linear motor technology the ServoTube is approximately 10 times as fast (5.9 m/s) as a typical ball screw and much quieter. When used with a matching Copley Controls digital amplifier such as the Xenus (photo), ServoTube actuators form a complete “plug and play” positioning subsystem.

Traditional pneumatic actuators can become very complicated to program, requiring elaborate control valves and a complex electro-pneumatic control system to choreograph the positioning function. By comparison, Copley’s intuitive indexing software is used to tune and program a drive system quickly and easily. A PLC can be used to initiate the Xenus’ stored motion profiles, simplifying the integration of the ServoTube into existing positioning systems.

ServoTube continuous force ranges from 51N to 104N with a peak force of 780N. The actuator is capable of a maximum 586 m/s2 acceleration, and 6m/s velocity at a resolution down to 12 microns. The actuator produces a 1V pk-pk sin/cos analogue position signal for simple integration into a variety of systems.
