Improvement of the Angular-dependent Noise in a Magneto-striction Type Torque Sensor
We proposed a new detection method for a magnetostriction-type torque sensor based on the iteration of the periodic time difference, and showed the evaluation results of its application to the rotation torque measurement of a shaft.

| description | We proposed a new detection method for a magnetostriction-type torque sensor based on the iteration of the periodic time difference, and showed the evaluation results of its application to the rotation torque measurement of a shaft. For practical use, however, it is essential to reduce the angular-dependent noise. Therefore, we next investigated making a uniform material surface for the noise reduction. In this paper, the experimental results of the improved sensor by making the material surface uniform are described. In addition, a sensor configuration that can reduce sensor drift and hysteresis is presented. As a result, it is shown that the angular-dependent noise and sensor drift can be decreased to less than 2 bits of digital output. |
