Saietta Group plc, the specialist e-mobility propulsion based at Upper Heyford in Oxfordshire, says that its Axial Flux Technology (AFT) electric motors have been shown to provide greater efficiency while also being light, compact and easily integrated into a wide range of e-mobility applications.
There is a significant and growing demand to make EV technology more accessible. Affordable electric propulsion and battery systems are key to reducing EV cost and enabling widespread adoption. This is an essential step for many emerging economies and cities that are gripped by chronic air pollution, especially in Asia.
Within these regions, the most common forms of transport are lightweight two-, three- and four-wheeled vehicles, which are used by millions of people daily. Following extensive market research, Saietta believes the fastest way to tackle the emissions crisis is to provide viable electric motor alternatives for small, internal combustion engine powered vehicles.
Heralded as an enabler of widespread electrification, Saietta says its first AFT e-motors – the AFT 140 and AFT 110 – offer greater efficiency while providing a reliable, cost-effective propulsion solution with zero tailpipe emissions.
Saietta’s testing programme saw a fleet of two-, three- and four-wheeled demonstrator vehicles retrofitted with the AFT. The scooters, motorcycles, rickshaws, last-mile delivery vehicles and micro-cars have all helped to highlight the versatility and reliability of the AFT e-motor. Following rigorous testing on the 20 miles of private roads at Saietta’s location in Oxfordshire, the AFT has been fully optimised for the lightweight EV spectrum.
Another pain point for EV manufacturers is motor and controller integration. Saietta addressed this by developing the AFT to be integrated with a broad range of off-the-shelf controllers.
With the AFT now in low volume production, Saietta’s engineering team is finalising the development of a new, high-voltage variant intended for high-performance vehicles.
Wicher Kist, Chief Executive of Saietta Group plc, said: “Saietta is intent on helping the world go further, accelerating toward a cleaner, more sustainable and prosperous future. Through widespread EV adoption and emissions reduction, cities around the world will be radically transformed, from Jakarta to Mumbai, Shanghai to Cairo.
“We recognise just how critical accessible electrification for lightweight vehicles will be in achieving these aims and we are addressing key market challenges by developing new, leading-edge electric propulsion technologies. Our AFT motors are compact and light while delivering high torque and efficiency at low voltage. This will enable vehicle manufacturers to reduce the required battery size for a given range and, in turn, use less rare materials in their construction.
“Specifically designed for highly automated production, our AFT motors are intended to make lightweight EV adoption more viable by reducing total vehicle cost. They are incredibly versatile and easily integrated into vehicle platforms. By providing the e-mobility solutions of today, we are building momentum towards a more sustainable, electrified tomorrow.”
