8LV servo motor series expanded for high-performance

B and R Industrial Automation has expanded the 8LV servo motor series to feature more steps per revolution in a smaller package.


The B&R Automation 8LV servo motor series has been expanded to include additional high-performance products. All mechanical and electrical elements in this series of servo motors have been integrated into a compact unit. Equipped with an absolute encoder system with a resolution of 262,144 steps per revolution, the system is able to achieve the high precision while taking up the least amount of space.

To save weight, installation space and the amount of mass being moved, gearboxes are mounted directly on the motor. This new mounting system was made possible by totally reconstructing the motor's output flange and adapting it completely to the gearboxes. The center gear rests directly on the motor shaft and replaces the input shaft on the gearbox. This type of mounting renders an adapter flange, the clamp system and the gearbox input bearing obsolete. In addition to an approximately 20% savings in weight and installation space, the amount of mass that has to be moved is considerably reduced as well.

Because of the rigid structure and the small amount of mass, high-performance control loops can be created for dynamic applications, even in tight spaces.

With gearboxes that are mounted directly on the motor, it's possible to select between the 8GM30 economy series, the 8GM40 standard gearboxes and the 8GM50 reinforced gearboxes. Gearboxes in the standard series are available as single-stage and two-stage units with a backlash <8 - <15 arcminutes. The 8GM50 series uses bearings optimized for radial and axial forces for mechanical compatibility with Wittenstein products.
