Title:
ROTATION DETECTING DEVICE AND ELECTROMOTIVE POWER STEERING DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/175843
Kind Code:
A1
Abstract:
The present invention provides a rotation detecting device provided with: first and second sensor elements which detect rotation of a subject to be detected; circuit units which respectively have first and second rotation angle calculating units which calculate rotation angles of the subject to be detected on the basis of first and second detection values respectively obtained by the first and second sensor elements, first and second rotation number calculating units which calculate the number of rotations of the subject to be detected on the basis of the first and second detection values, and first and second communicating units which output, to a control unit, rotation angle signals related to the rotation angles and rotation number signals related to the number of rotations; and a package unit which seals the first and second sensor elements and the circuit units, and is mounted on a substrate separately from the control unit.
