Abstract
The present invention relates to a torque sensor including an input axis, an output axis and a torsion bar connecting the input axis to the output axis, the torque sensor characterized by: a plurality of magnets connected to one of the input axis and the output axis of steering system, and axially magnetized for arrangement to a circumferential direction; and a stator including a ring-shaped body connected to one of the input axis and the output axis that is not connected to the plurality of magnets and discretely arranged from the magnets, and a plurality of lugs facing an axial distal end of the magnets, whereby a conventional collector is eliminated to allow a magnetic device to be directly coupled to a stator, thereby providing an operational reliability and structural simplicity.
