E+L launches AG 9 actuating drive

Erhardt+Leimer has launched AG 9, a new actuating drive for web guiding on unwinders, rewinders and in large pivoting frames.

Developed in-house and produced at the Erhardt+Leimer site in Augsburg, Germany, AG 9 was primarily designed for web guiding systems, however in principle it can be used in all applications that require a maintenance-free, highly dynamic linear drive with a large actuating force.

In combination with the command station DO 3001, the AG 9 is used for web guiding on unwinders, rewinders and in large pivoting frames. Ethernet networking with response times of 1ms and an actuating speed of up to 60mm/s ensure maximum actuating dynamics. Even at high reel weight, that allows optimal compensation of tumbling errors, for example. Control frequencies up to 4Hz are possible.

The actuating drive is available in two variants, with the AG 91 offering an actuating force of 1000N at an actuating speed of 60mm/s, and the AG 93 providing 3000N at 30mm/s. Actuating speed, actuating force and actuating travel can be adjusted as required.

Erhardt+Leimer said AG 9 is the only fully integrated actuating drive on the market with a brushless and, therefore, wear-free motor. The position is acquired via another unique feature, an integrated absolute encoder. This means no reference run is required on commissioning, and the current position of the actuating drive is not lost even if the power fails. The controller is also integrated in the actuating drive.

As the AG 9 is a direct drive device without gearbox, it is almost play-free in the axial direction. The device itself is highly compact, allowing it to be mounted even in tight spaces.

Erhardt+Leimer CEO Dr Michael Proeller said: ‘In almost the 100 years of the history of Erhardt+Leimer, the AG 9 represents our biggest development project yet. None of our competitors offers a comparable product, as such we are convinced the effort has been worthwhile.’
