YASA axial-flux motor wins Dewar Trophy
The Royal Automobile Club’s Dewar Trophy has been awarded to YASA for the development and commercialisation of its powerful yet compact YASA axial-flux motor.

The award was presented to Tim Woolmer, the company’s founder and CTO, at an event held on October 31, 2023, at the RAC Club in London.
In a statement, Ben Cussons, chairman of the Dewar Technical Committee, said: “YASA’s development of axial-flux motors captures the simple essence of this special award – an outstanding British technical achievement. It’s an engineering breakthrough that has evolved electric propulsion to the next level, and is likely to influence the cars we will drive in the future.
“YASA is also overturning the norms of materials technology and manufacturing processes, as it gears up to mass-produce its components.”
YASA, spun-out from Oxford University in 2009 by Woolmer while studying his PhD in engineering, employs 400 people in the UK and is recognised as a world-leading pioneer in electric propulsion technology. To date, the company has amassed 150 patents, and has also designed its own robots to build its products at two UK manufacturing plants.
