A team of MIT engineers is developing a 1MW motor that could be a key stepping stone toward electrifying larger aircraft. The motor under design is a 1-MW, air-cooled, outer-rotor, Halbach-array PMSM. The stator winding process and insulation have been successfully demonstrated through a mockup stator winding.

ExOne and Maxxwell Motors have successfully binder jet 3D printed a high-efficiency copper e-winding design for an electric motor without rare-earth magnets. Optimized copper windings and rotors in electric motors are among the factors enabling the automotive industry’s transition to hybrid and pure electric power vehicles.

Motivated by the need to eliminate expensive rare-earth magnets in utility-scale direct-drive wind turbines, Sandia National Laboratories researchers have developed a fundamentally new type of rotary electrical contact. Most of the current utility-scale wind turbines are dependent on rare-earth magnets, Koplow said. 1 milliohm).

Researchers at Fraunhofer IFAM have developed a casting technique that can be used to produce lightweight aluminum windings with a higher groove fill factor to replace copper windings in electric motors. To show this in a direct comparison, the Fraunhofer team used 250W commercial pedelec motors. © Fraunhofer IFAM.

In the 800-volt variant of the electric motor, Bosch has increased the power density. With the same current, but double the voltage, twice as much power can now be transmitted. As a result, the inverter is more compact and powerful. In power electronics, moreover, 50% less energy is lost in the form of heat.

Lucid Motors provided some details about it proprietary, in-house developed electric drivetrain that will power the forthcoming pure-electric luxury Lucid Air. With up to 1,080 horsepower available in a dual-motor, all-wheel-drive architecture, the Lucid Air is able to achieve quarter-mile times as low as 9.9
