Abstract
An aircraft system is provided that includes a first propulsor rotor, a second propulsor rotor and an electric machine. The first propulsor rotor is rotatable about an axis. The second propulsor rotor is rotatable about the axis. The electric machine includes a first electric machine rotor, a second electric machine rotor and an electric machine stator radially between the first electric machine rotor and the second electric machine rotor. The first electric machine rotor is rotatable about the axis and rotatably connected to the first propulsor rotor. The first electric machine rotor and the electric machine stator form a first motor configured to drive rotation of the first propulsor rotor. The second electric machine rotor are rotatable about the axis and rotatably connected to the second propulsor rotor. The second electric machine rotor and the electric machine stator form a second motor configured to drive rotation of the second propulsor rotor.
