Friction disc plays important role in revolutionary hybrid brake technology

A LEADING European robotic innovator is now manufacturing hi-tech surgical robots which use our friction discs to assist with their brake technology.

The first-of-its-kind hybrid permanent magnet and spring applied brake has been designed by SG Transmission, an electromagnetic clutch and brake manufacturer in the North East of England.

Due to the critical nature of the application, the pre-assembled solution features both spring applied and permanent magnet technology – providing double redundant capability in the event of a failure.

Designed for a range of small, next-generation and multi-axis surgical robots; the hybrid solution benefits from both technologies – by combining the high torque and backlash-free capability of a permanent magnet brake with the extended temperature range of a spring-applied brake.

Our friction disc, which is made from a compression mould, forms a key part of the braking system application.

Barry Davidson, General Manager at Fairgrieve Compression Moulding, said: “It’s pleasing to know that we have played a small but essential part in such a revolutionary piece of braking technology.

“We’ve been working in partnership with SG Transmission for a number of years now and it’s great to see their innovative business going from strength to strength.”

The design team at SG Transmission worked closely with the customer throughout the project to align their electromagnetic knowledge with the requirements of the application.

Andy Collinson, Chief Executive Officer at SG Transmission, said: “We are committed to our position in the industry as the expert in bespoke electromagnetic solutions, and this project has provided the opportunity to add yet another pioneering design to our catalogue.”
