A rotary propulsion system includes a fan arranged along a rotation axis, an electric motor having windings and a permanent magnet arranged along the rotation axis and operatively connected to the fan, and a reduction gear set. The reduction gear set extends about the rotation axis and couples the electric motor to the fan. The permanent magnet is rotatable relative to the windings and the fan to rotate the fan using the electric motor at a rotational speed that is lower than a rotational speed of the permanent magnet. Aircraft and methods of propelling aircraft are also described.
