High Frequency Direct-Drive Electric Propulsor
About the Machine
Our high frequency direct-drive machine features best in class electro-magnetic performance with a 98% efficiency, and highest in class specific power of 11 kW/kg.
This machine was designed for the NASA STARC-ABL future hybrid electric aircraft in a tail-cone propulsor configuration. This outer-rotor machine features a high pole count to achieve high efficiency and boasts an air-cooled stator. Learn more about our machine here.
How It Works
Fault Tolerant Design
Our machine features a segmented coil arrangement with distributed power electronics to prevent mission critical failure. In event that an electronic subsystem fails, our machine will still propel the aircraft to a safe landing.
Halbach Array
We use a Halbach array to contain our magnetic field and eliminate heavy magnetic insulators. This allows us to efficiently use our magnetic field to produce high torque.
Air Cooling
Our high-efficiency machine allows us to use air to cooling for our machine. This eliminates the need for heavy liquid circuits.
