DEVICE FOR DETECTING ROTATION ANGLE AND TORQUE

摘要

A rotation angle and torque detection apparatus includes: a target having magnetic poles magnetized at an outer circumference face so that the magnetic poles have alternately-different polarities and the target can be rotated multiple times; and a detector that is positioned to have a fixed distance from the target in a radial direction of the target and to have a fixed distance from the center of the target in an axial direction and that is provided at a plane vertical to the radial direction of the target. This rotation angle and torque detection apparatus can sense a torque and a multiple rotation angle with high resolution and high accuracy.
