1. A trimmable horizontal stabilization actuator of an aircraft, the trimmable horizontal stabilization actuator comprising:
a linear actuator, the linear actuator comprising:
a screw shaft having a shaft axis (A);
a nut assembly mounted to the screw shaft to move linearly along the screw shaft as the screw shaft is rotated; and
a motor to rotate the screw shaft without a gear, wherein the motor is an axial flux motor, wherein the axial flux motor is mounted to the screw shaft such that flux generated by the axial flux motor is parallel to the shaft axis (A).
