Electric tubular motors offer alternative to pneumatic actuators

Parker’s Electromechanical Division Europe has introduced the ETT Electric Tubular Motor series for linear handling and pick-and-place applications.

As the ETT is a ‘direct drive’ actuator, motion is generated without the need for mechanical transmission elements such as ball screws, toothed belts or gearboxes – all of which can have an impact on installation, operation and maintenance costs.

Another feature of the ETT is its suitability for high duty cycle operation without the need for additional cooling, thanks to its high thermal efficiency. ETT can be controlled by any standard servo drive and 230Vac supply, and there's a range of servo drive options suitable for use with these motors.

The ETT series offer suitable substitution for pneumatic cylinders. To aid ease of integration, three lengths and sizes meet the requirements of the pneumatic ISO flange standard DIN ISO 15552:2005-12. Furthermore, swivelling electrical connectors and accessory options support flexible mounting, particularly in combination with a wide choice of rod end mounting choices.

Performance features include thrusts of up to 512N, travel speeds of up to 4m/s and acceleration up to 200m/s². A repeatability of ±0.05mm achievable thanks to the use of a 1Vpp sine/cosine encoder.
