摘要： A compound harmonic actuator is provided and includes a motor (101), a flex spline (102) disposed about the motor and a wave generator (103) radially interposable between the motor and the flex spline. The wave generator being rotatably drivable by the motor and shaped to form the flex spline into an elliptical shape with an axis such that wave generator rotations drive rotations of the axis of the ellipse of the flex spline.

摘要： Aircraft electric motors are described. The aircraft electric motors include a cooling system (204) comprising an annular heat exchanger (226), a motor housing (202) arranged radially inward from the heat exchanger, the motor housing defining a rotor-stator cavity and a gear assembly cavity, a rotor sleeve (216) arranged within the rotor-stator cavity, a gear assembly (224) arranged within the gear assembly cavity, a first shaft (220) operably coupled to the rotor sleeve and configured to be rotationally driven by the rotor sleeve to drive rotation of a portion of the gear assembly, and a second shaft (222) operably coupled to the gear assembly and configured to be rotationally driven by the gear assembly.

摘要： 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).
