Robots which save space, and extract heat more efficiently

Lower Saxony is confidently advertising its own innovative strength something, which is most apparent in its robotics expertise. The region’s claims to market leadership were once again made clear at the Hannover Messe  2018. The company exhibited a number of robots for performing various load-carrying tasks. Inside, they are powered by specially customized servo motors from KOLLMORGEN’s KBM range. The powerful synchronous machines are frameless and can be embedded in the construction of the robot straight from the kit. The main advantages of this are that it saves space, and heat can be extracted far more efficiently.

Dr. Jens Kotlarski likes to lead his new robots by the hand. “In the same   way as I would show things to my child, I show them to the machine,” says the managing director of Yuanda Robotics GmbH – a successful spin-off set up by three scientists from the Leibniz University in Hannover with funding from the Shenyang Yuanda Aluminium Industry Group in China.

High Power Density :

This is where the frameless structure of the KOLLMORGEN KBM motors can improve heat extraction simply by convection across the robot’s joints. The effect of these excellent thermal properties is that the KBM motors can reach peak performance without derating.

Quick delivery for quick start-ups :

The short delivery times for the frameless motors in the KBM series are mainly possible because each bespoke drive system is the result of a clever combination of standard components. Refinements can be made, for example, to the rotor hub dimensions, stack length, diameter, assembly jigs, windings, connection type, and much more.

The Bottom Line :

With their new series of robots, the company from Hannover is marketing a solution that provides everything that is needed to automate assembly and handling tasks quickly and reliably. The overall package is nicely rounded off by the integrated camera technology in the robot. This enables the robot to identify the products it needs to pick up by itself. For the visualization, the company has taken advantage of the potential of so-called augmented reality. This means that, when the parameters for new tasks are being set, the movements of the robot in the workspace can be exactly simulated – and then they can be sent out to start production.
