Fail-Safe spring applied brake with slim design

The spring-applied brakes which are ideally suited for robotics is designed for robotics solutions and loads of up to appr. 20 kg, but it can also be used in other applications requiring small geometrical dimensions. With regard to their power density the slim single-disc brakes are flatter and lighter than the market standard, and due to their large inner diameter they are well suited for hollow-shaft drives. This makes them perfect for applications in lightweight robots with integrated drives.

The optimal solution for robotics
There is a growing demand for safety technology in order to avoid injuries by collisions, especially if the control technology or even the power supply fails. In this case electromagnetic brakes are usually the method of choice. As safety brakes they bring moving masses to a stop, keep loads in position and therefore prevent humans and material assets from being affected.

For decades Kendrion has been supplying brakes for industrial robots with loads higher than 20 kg. In order to be able to serve the booming market of smaller robots the brake specialist has invested a lot into the research and development of suitable brakes for robotics applications in recent years. With many years of experience and the latest findings from the market ideally suited solutions for robotics have been developed.

Manufacturing technology

A patented manufacturing technology provides the basis for this solution: In case of conventional spring-applied brakes the production-related tolerances of the air gap, i.e. the distance between friction disc and armature plate, must be taken into account
