Parker’s Electric Thrust Tubular (ETT) Series is a tubular style linear motor made up of two main components: the stator with integrated analog Sin/Cos feedback 1 peak-to-peak voltage as standard (other standards are optional), and the rod, a stainless-steel AISI304 shaft with neodymium magnets. This allows for high-speed acceleration. Using linear-motor technology eliminates the need for an additional belt or screw, gearhead, and motor as in many electromechanical positioners. Tubular linear motors suit any pick-and-place or linear handling application that requires high dynamic positioning.

Tubular linear motors have some interesting advantages in typical applications, including no wear components, no seals to fail, and flexible control. This model incorporates iglidur X guide bearings from igus for high speed and high temperature ranges, and a Class H coil with three-phase standard brushless design and 1000-V winding insulation. The unit also features a DIN ISO 15552:2005-12 mounting footprint for integration into existing mounting contingencies.

This construction serves a number of different industries and applications, such as conveyor diverting, indexing, and pick-and-place, among others. Fully potted and sealed motor coils and rod deliver an IP67 rating, enabling it to handle harsh, wash-down applications.
