eVTOL axial-flux electric motor pioneer Evolito receives CAA Design Organisational Approval

Evolito Limited, a developer of axial-flux electric motors, power electronics and battery solutions for aerospace applications, has received Design Organisation Approval (DOA) from the UK Civil Aviation Authority (CAA) for electric propulsion system products.

“The CAA’s approval of Evolito as a Design Organisation demonstrates that it is satisfied that Evolito has the technical expertise, facilities and capabilities to design safe and reliable products, and is able to comply with stringent requirements for certification,” according to a company press release. “Evolito is the first company in the UK to achieve this for electric propulsion systems. This accreditation is a significant milestone towards certification of Evolito’s products, as well as supporting customer requirements to certify their electric and hybrid aircraft. Type Certification is necessary to prove an electric aircraft, its propulsion system or propeller are safe for commercial use.”

The DOA process was initiated in autumn 2022, with assessments of the company’s organisation and procedures and concluded with the signed approval in October 2023.

Gareth Morris, Chief Operating Officer at Evolito, said: “While this DOA takes Evolito one step closer to Type Certification, it’s also an important step for the electric aerospace industry, further accelerating the commercialisation of electric flight.”

“Evolito’s unique axial flux electric motors, which are proven in rate manufacture offer class-leading torque densities and system efficiencies, best matched to propeller speeds used in eVTOL, UAV and fixed-wing aircraft applications,” continued the press release. “The Evolito motor topology is inherently safer and more robust as compared to alternative motor types. Combined with the battery systems and high integrity motor control unit capabilities, Evolito creates propulsion solutions that at are optimised for the aircraft business case.”
