Leading Sheffield based green tech company Magnomatics attended the Driving the Electric Revolution (DER) Engage with LIVE! event at the Octagon at the University of Sheffield and displayed a 500kW direct drive generator for offshore. An apt tribute to an exciting new and novel technology invented at the University.

The 17-tonne generator was recently re-tested at the Offshore Renewable Energy Catapult in Blyth as part of the WindER project, co-funded by the DER Catalysing Green Innovation round. Data from the tests has been used in the second iteration of the development.

In November 2017 the InnWind Project ( identified Magnomatics technology as ‘very promising’ for the next generation of offshore wind in the 10 to 20MW range. The desk-based study highlighted that a magnetically gear motor could lower the levelized cost of energy by around 3%. This conclusion was verified with the build and test of the 500kW demonstrator as part of the DemoWind project funded by Horizon 2020.

A demonstration machine was built by Wolong Laurence Scott in Norwich and tested at the ORE Catapult. As a result of these tests Magnomatics provided a leading global engineering company with exclusive access to the technology for the sector.

The Advance Manufacturing Research Centre (AMRC) in Sheffield has also played an important role in the development of the generator. In a project that was co-funded by the Offshore Wind Growth Partnership they developed a method to build large magnetic rotors using robots. This delivered a 60x increase in productivity!

Magnomatics’ CEO Dave Latimer commented: “It was fantastic to see our technology showcased at the DER event. Grant funding has been an enormous help to us and we are now well down the road to commercial success. Especially exciting given this generator was born in Sheffield”.

Committed to playing their part in the road to net zero, Magnomatics is a high-technology company formed in 2006 as a spin out from the University of Sheffield. The company is commercialising novel products based upon highly efficient proprietary magnetic gear technology.
