DAANET (www.daanet.com.au) has expanded its B&R’s 8LV servo motor series portfolio to include a new range of motor-mounted gearboxes.
The high-performance servo motors offer high power density in a small installation space and integrate all electrical and mechanical elements into a very compact unit.
Designed with a very small absolute encoder system offering a resolution of 262144 steps per revolution, the system can achieve high precision while occupying lesser space.
The gearboxes are directly mounted on the motor to save installation space, weight and the amount of mass being moved, made possible by a total reconstruction of the motor’s output flange and its adoption to the gearboxes.
The center gear directly rests on the motor shaft and substitutes the input shaft on the gearbox. This kind of mounting eliminates the need for a clamp system, adapter flange or the gearbox input bearing.
Aside from saving approximately 20% in installation space and weight, it also reduces the amount of mass that has to be moved.
Creating high-performance control loops for dynamic applications is also possible even in tight spaces with the small amount of mass and rigid structure.
With gearboxes directly mounted on the motor, it is possible to choose from the standard 8GM40 gearboxes, the economy series 8GM30 gearboxes and the reinforced 8GM50 gearboxes.
The 8GM50 series uses optimized bearings for axial and radial forces for mechanical compatibility with Wittenstein products.
The latest motor series is suited for applications with high demand on torque and dynamics in limited spaces.
