AML set to push ahead electric aviation

AML High Power Density Motor

AML’s electric propulsion shows more than 30% higher performance during high-volume production

AML Superconductivity & Magnetics (AML), a developer of magnet-based applications, has launched an electrical machine development programme designed to produce propulsion motors for the aviation and aerospace sector. The programme is inspired by the fact that motors are the heart of electric propulsion while magnets are the heart of motors.

While electric vehicles and other industries are expected to command the major share of the need for motors, AML believes its innovation holds the key to the future of aviation.

“This may be the holy grail for the electrification of aviation,” Dr. Rainer Meinke, co-founder and CTO of AML, said.

“We are excited to specifically focus on this multi-billion dollar market where size and weight are fundamental for electric propulsion to be successful as a viable transport system,” said Mark Senti, co-founder and CEO of AML.

The programme applies AML’s proprietary technologies, including the CoilCAD™ software to deliver ultra high-power, lightweight motors and generators that achieve unprecedented magnetic flux density without traditional back iron. AML has also developed a stator system that optimises reliability, overload allowance and redundancy compared to existing electrical machines.

“Our software allows customers to explore thousands of design solutions for the most optimised configuration and the magnets inside,” Senti said.

“Over the course of the next 18 months, we expect to achieve unmatched progress with commercially viable electrical machines for aircraft,” said Dr. Meinke.

Scalability of the project is ensured with PM-Wire, a novel technology for manufacturing permanent magnets that reduces cost, waste, and time, while increasing safety and performance.

The global market size for motors and related components was estimated at US$118 billion in 2017 with expected growth to over US$200 billion by 2025. The leading consumers of motors include electric vehicles and industrial machinery at over 60% combined. The aerospace market grabbed about 6% market share in 2017 and is projected to remain through 2025.
