Axial-flux: a revolutionary new approach

Building on YASA’s IP, Evolito is enabling the aerospace industry to leave behind the legacy radial electric motor technology that’s been holding the market back, and with this unique technology allowing it to truly take off.

 

“We’re building the future of electric flight with motors that have the highest power and torque densities in class with the ability to manufacture at scale, whilst achieving efficiencies of over 98%.”

Gareth Morris, Managing Director, Evolito

 

Our axial-flux motor’s unique segmented topology and novel cooling systems are also inherently more robust than other electric motors systems, making them ideally suited to aerospace applications.

Smaller. Lighter. Faster.

Our axial-flux technology also requires up to 75% less iron, less copper and less permanent magnets than competing radial solutions, making it lighter and more environmentally-friendly.

Our current products include YASA P400 & YASA 750 but our range is expanding with new products that will take another leap forward in power densities and performance for the aerospace market.

Evolito provides the world’s most advanced direct drive & in-direct drive electric propulsion solutions for Fixed-Wing and EvToL applications.

 

The Urban Air Mobility (UAM) market alone is forecast to grow to over $100 billion by 2035.

 

However, the success of this potentially transformative but still nascent market will depend on the market’s adoption of new technologies. Current approaches to electric flight rely on legacy radial motors — a technology that is over 50 years old, with very little innovation roadmap left ahead.

 

In comparison, Evolito’s axial-flux electric motors and power electronics have the highest power densities and greatest efficiencies in class, making them ideally suited for new all-electric aerospace applications.

 

In addition, the technology is already established in the electric automotive market, being deployed in series production by manufacturers including Mercedes-Benz and Ferrari. This proven rate of manufacture and process quality allows for the potential for scalable manufacture from the outset
