Title:
ROTATION ANGLE DETECTOR
Document Type and Number:
WIPO Patent Application WO/2007/119701
Kind Code:
A1
Abstract:
A rotation angle detector comprises a shaft part having a torsion bar, a rotation angle detection part for detecting the rotation angle of the shaft part, and a torque detection part for detecting the twist angle of the torsion bar. The detection accuracies of the rotation angle detection part and the torque detection part themselves can be enhanced by mutually utilizing the results of respective detections. Thereby, the detector can detect the rotation angle and the twist angle of a rotating body which does multiple rotations with high accuracy and high resolution power.
