<p>Disclosed are a torque sensor for measuring torsion of a steering column, configured to allow a magnetic flux of a stator unit magnetized by a magnet to flow in one direction, thereby minimizing a hysteresis loss and increasing measurement accuracy, and a measurement method using the torque sensor. In the torque sensor for measuring torsion of the steering column to which an input shaft and an output shaft are coaxially connected, any one of the input shaft and the output shaft may include a rotor unit including a plurality of magnets and the other one may includes a stator unit including teeth respectively corresponding to the plurality of magnets. The rotor unit and the stator unit allow a magnetic flux to flow in one direction, and measure torsion of the steering column by detecting density of the magnetic flux flowing in one direction.</p> |
