Abstract: A rotor assembly of a torque sensor includes: a rotor having a through hole formed along an axial direction so that a steering shaft can be inserted in the through hole; a gear having substantially a ring shape and coupled to the rotor; and a fixing portion configured to fix the rotor to the gear. The fixing portion includes at least one first coupling portion configured to fix the rotor to the gear with respect to the axial direction, and at least one second coupling portion configured to fix the rotor to the gear with respect to a rotation direction. Each of the first coupling portion includes an elastically deformable hook bent from the rotor, and a hook groove penetrating the gear or being depressed from a surface of the gear in a radial direction, such that the hook is inserted in and caught by the hook groove.

Abstract: 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.
