Aircraft electric motors are described. The electric motors include a substantially annular shaped motor housing (800) having an outer wall (802) and an inner wall (804), wherein a rotor-stator cavity (806) is defined between the outer wall (802) and the inner wall (804) and a gear assembly cavity (812) is defined radially inward from the inner wall (804) and a gear assembly (702) arranged within the gear assembly cavity (812). The gear assembly (702) includes a sun gear (720) operably connected to a first shaft (716), at least one planetary gear (728) arranged radially outward from the sun gear (720) and rotationally engaged with the sun gear (720), and a ring gear (732) arranged radially outward from the at least one planetary gear (728) and rotationally engaged with the at least one planetary gear (728), wherein the ring gear (732) is operably connected to a second shaft (722).
