A position sensor includes a substrate having a first surface and a second surface opposite to the first surface; an initial shaft passing through the first and the second surfaces of the substrate in a direction perpendicular to the substrate; an initial gear mounted to the initial shaft and positioned above the first surface of the substrate; a first sub-shaft positioned above the first surface of the substrate, and disposed perpendicular to the substrate and parallel to the initial shaft; a first sub-gear mounted to the first sub-shaft and positioned above the first surface of the substrate and rotatably engaged with the initial gear; a first sub-rotor mounted to the first sub-shaft and positioned above the first surface of the substrate; a first sensing coil disposed on the first surface of the substrate; a second sub-shaft positioned above the first surface of the substrate, and disposed perpendicular to the substrate and parallel to the initial shaft and the first sub-shaft; a second sub-gear mounted to the second sub-shaft and positioned above the first surface of the substrate and rotatably engaged with the initial gear; a second sub-rotor mounted to the second sub-shaft and positioned above the first surface of the substrate; and a second sensing coil disposed on the first surface of the substrate.
