Oxford YASA Motors expanding to meet growing demand

Less than two years after spinning out of Oxford University, Oxford YASA Motors (earlier post) is expanding, moving from Abingdon in Oxfordshire to a new facility at Milton Park. The phased relocation will be completed in the first quarter of 2012.

Oxford YASA Motors produces the innovative YASA (Yokeless And Segmented Armature) motor which delivers 40 N·m/kg—the highest torque-to-weight ratio available on the market—in a versatile package that is suitable for high volume production.

The YASA is a new type of axial flux motor that has no stator yoke, a high fill factor and short end windings which all increase torque density and efficiency of the machine.

Engineers are currently working on the next generation YASA motor, optimized for power density, which will achieve 10 kW/kg, again a significantly higher ratio than competitor motors. The YASA motor powers leading-edge high performance vehicles including the Delta E-4 all-electric coupé from Delta Motorsport.

High torque electric motors are increasingly viewed in motor racing as the most efficient method of delivering quick acceleration. Over the next 12 months, Oxford YASA Motors will be installing systems into the Westfield iRacer and TT-XGP motorcycles.

The company is continuing to develop new markets for hybrid and electric vehicles, through ongoing collaborations with Delta Motorsport and Morgan Motor Cars in the UK, plus Electroengine in Sweden.



At 10 Kw/Kg, these motors will help to make electrified vehicles lighter and more efficient. Less weight will mean less batteries for a given e-range.
