Abstract (en)

[origin: WO2021112940A1] An integrated electric propulsion assembly includes a stator including at least a first magnetic element generating first magnetic field. The assembly includes a propulsor with an integrated rotor, the propulsor further including a hub rotatably mounted to the stator and at least a second magnetic element affixed to the hub, the at least a second magnetic element generating a second magnetic field. At least one of the first magnetic field and the second magnetic field varies with respect to time, wherein the varied magnetic field includes generating a magnetic force between the at least a first magnetic element and the at least a second magnetic element, and the magnetic force causes the hub to rotate with respect to the stator.
