Title:
TORQUE MEASUREMENT APPARATUS USING A NONCONTACT MAGNETIC SENSOR
Document Type and Number:
WIPO Patent Application WO/2012/093749
Kind Code:
A1
Abstract:
The present invention relates to a torque measurement apparatus using a noncontact magnetic sensor. The torque measurement apparatus may be variously applied to industrial fields in which torque control is required because adequate torque can be set at a fine range according to the use and purpose of the apparatus which is also miniaturized. Thus, in the torque measurement apparatus, a hole sensor for detecting a signal of a magnetic field is provided, and a rotation operable body and an elevation operable body are assembled with each other within a cylindrical housing to allow the rotation operable body and the elevation operable body to be rotated together with each other. Here, the rotation-operable body may have a variable rotation angle within the housing by modulus of elasticity of a spring due to external resistance during the rotation. The elevation-operable body may include a plurality of magnets arranged at the same distance to each other and be elevated within the housing according to a change in the rotation angle of the rotation- operable body so as to get closer to the hole sensor. Thus, the magnets may get closer to the hole sensor to detect a torque value.
