Electric Thrust Tubular (ETT) Linear Motor

Parker’s Electromechanical Automation Division, a leading supplier of motion control technology, is pleased to announce the release of the Electric Thrust Tubular (ETT) linear motor actuator series. Parker’s ETT is a tubular-style linear motor offering a unique solution for machine builders, OEMs, and users alike. The body of this actuator houses the motor stator, with the magnets embedded in the moving rod, making it a direct-drive, rod-style thrust actuator. The ETT is characterized by its high speed, high acceleration, and dynamic positioning capability, giving superior control and lower overall cost of ownership as compared to typical pneumatic positioners, due to its high efficiency and overall energy savings. Having full compliance with the DIN ISO 15552:2005-12 mounting standard ensures simplicity of mechanical integration of the ETT and reduces overall design complexity. A wide variety of optional accessories are available for the ETT to facilitate ease of mounting.

The ETT’s linear motor technology eliminates the need for an additional belt or screw, gearhead, and motor as in many electromechanical positioners, creating greater performance in a smaller overall package. This reduction of components also serves to mitigate overall system cost and reduce installation costs. By eliminating bearing components, potential wear items are removed, equating to drastically reduced overall maintenance. The high thermal efficiency of the ETT gives it high reliability and greatly extended life characteristics and makes it ideal for high-duty-cycle applications.The ETT comes standard with IP67 protection for harsh, wash-down environments. The 1 VPP Sin/Cos encoder feedback allows for high resolution and can be paired with any standard servo drive with 230 VAC supply voltage. Parker offers a wide range of servo drive options that are ideal for use with the ETT, enabling customers to obtain the complete motion solution from one supplier. The ETT is ideally suited for any pick-and-place or linear-handling application requiring high dynamic performance.ETT Electric
