A servo motor alternative to pneumatic cylinders
The electric cylinders in Beckhoff’s AA3000 series are ideally suited to operate as direct drives for linear ap- plications with high process forces and speeds. The ad- vantages in terms of force, dynamics and compactness are combined with the advantages of servo technology such as controlled positioning, safe holding at a standstill and high energy efficiency. The integrated mechanism of precise roller bearings, ball screw and guide provides for a backlash-free, pure- ly translatory motion. This results in compact dimen- sions. At the shaft end of the spindle there is an exter- nal thread on which conventional adapters such as ball heads or clamping hooks from the pneumatic/hydraulic range can be mounted. The first product of the new series is the AA3033 elec- tric cylinder, which is available in two variants: - with 12 500 N peak force, 3 700 N continuous force and 0.5 m/s maximum speed, or - with 6 250 N peak force, 1 850 N continuous force and 1.0 m/s maximum speed. The flange size of the electric cylinder is based on ISO 15552 and has bolting points on both sides in case, for example, an application requires a swivel bolt connection. This compatibility makes the conversion
from pneumatic to electric drive technology particularly easy. In addition to the high resolution, the safe 24-bit multi-turn encoder installed offers the advantages of one cable technology (OCT) and the electronic identification plate for fast and simple commissioning. In addition, the electric cylinder enables uncomplicated access to process data, which can be used to optimise process performance quickly and easily. Other spindle pitches or a backlash-free holding brake are available as options. For more information contact Beckhoff Automation.
