History
YASA Limited (formerly YASA Motors Limited) was founded in September 2009 to commercialise a permanent-magnet axial-flux electric motor (YASA stands for Yokeless and Segmented Armature). The motor was developed for the Morgan LIFEcar in 2008 by Dr Malcolm McCulloch and Dr Tim Woolmer, then a PhD student, at the University of Oxford.{{cite web|title=Special commendation: Electric avenue|url=http://www.theengineer.co.uk/special-commendation-electric-avenue/1000288.article|publisher=The Engineer|access-date=4 March 2015}} In 2015, YASA Motors launched the P400 Series of motors in serial production for volume manufacturers.{{cite web|last1=YASA Motors|title=YASA Releases New Motor and Generator Products for Serial Production.|url=https://www.yasa.com/news/yasa-p400-series-launch/|website=yasa.com|date=15 September 2015 |access-date=15 October 2015}} In January 2018, YASA's 1st series production facility, capable of 100,000 units per year, was officially opened{{cite news|title=Electric vehicle motor factory opens in Oxfordshire|work=BBC News |date=February 2018 |url=https://www.bbc.co.uk/news/uk-england-oxfordshire-42891960|access-date=14 August 2019}} by Greg Clark, UK Secretary of State for Business, Energy and Industrial Strategy.
