Advanced Magnet Lab, Inc. has announced that the U.S. Department of Energy's ARPA-E has nominated AML for the development of advanced lightweight and ultra-efficient electric propulsion for electric aircraft.

FREMONT, CA: Advanced Magnet Lab, Inc. has announced that the U.S. Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E) has nominated the company for the development of advanced lightweight and ultra-efficient electric propulsion motors, drives, and associated thermal management systems. This equipment can be utilized in commercial electric aircraft.

The program has combined AML's novel permanent magnet rotor and stator technology with integrated power electronics and cooling. The system can offer power densities beyond 12 kW/kg for the fully electric drivetrain. Nowadays, the aircraft utilizing gas-burning turbine engines can accomplish almost 6-9 kW/kg.

Such alteration from gas to electric propulsion needs innovative technologies and several breakthroughs to enhance energy efficiency and decrease carbon dioxide emissions, nitric oxide pollutants, and noise levels.

However, AML and its team have planned a solution with the following elements:

• Improved cooling that allows high current density stator coils

• Shared closed-loop cooling system

• Permanent dual magnet rotor constructed on AML's PM-360 "¢ magnets

• High-power density power converters

The innovative approach of AML is based on a revolutionary magnet technology known as PM-360. It can considerably increase the performance of magnet-based products at a competitive cost. AML's solution integrates a dual PM-360 rotor for electric propulsion than can offer optimal motor performance and abolishes iron that can be utilized in conventional motors.

The program's ultimate objective is to create an advanced lightweight and ultra-effective electric motors, drives, and the related thermal management systems (cooperatively stated to as the all-electric powertrain). It will help to allow net-zero carbon emissions in commercial aircraft. Moreover, the single-aisle and twin-aisle aircraft can also carry 100 or more passengers account for more than 90 percent of global emissions from commercial aircraft.

DR. Philippe Masson, CTO of AML, stated, "We are extremely excited to be provided the opportunity to develop and exhibit our capabilities and technologies for the future of aviation."
