Yet another efficient electric motor gets commercial interest

Oxford Yasa Motors Ltd. (Yasa stands for "Yokeless And Segmented Armature") developed its electric motor for a high-performance hydrogen car. The motor's claim to fame is an ability to develop twice the torque in half the space of comparable devices. Now it looks as though the design is close to commercialization.

Yasa has closed a £1.45 million funding round with private investor Seven Spires Investments Limited and says it has been successful in securing a grant from the UK’s Technology Strategy Board as part of a £1.89 million consortium to develop a higher volume version of the motor.
