PROBLEM TO BE SOLVED: To provide a rotation detector which can continue operations related to the rotation of a detection target if an abnormality has occurred in a part of a circuit, and an electrically-driven power steering device using the rotation detector.SOLUTION: A rotation detector 1 has sensor elements 601 and 602 detecting rotations of a motor unit 10. A circuit unit 610 has a rotational angle operation unit 615, a rotation number operation unit 616, and a communication unit 617. A circuit unit 620 has a rotational angle operation unit 625, a rotation number operation unit 626, and a communication unit 627. A package 65 seals the sensor elements 601 and 602 and the circuit units 610 and 620, and is equipped to a first base substrate 21 separately from the microcomputers 51 and 52. This enables the operation of a rotational angle θm and the number of rotations TC to be continued if an abnormality has occurred in a part of the circuit units 610 and 620.SELECTED DRAWING: Figure 9

    【課題】回路の一部に異常が生じた場合にも検出対象の回転に係る演算を継続可能である回転検出装置、および、これを用いた電動パワーステアリング装置を提供する。【解決手段】回転検出装置1のセンサ素子601、602は、モータ部10の回転を検出する。回路部610は、回転角演算部615、回転回数演算部616、および、通信部617を有する。回路部620は、回転角演算部625、回転回数演算部626、および、通信部627を有する。パッケージ65は、センサ素子601、602および回路部610、620を封止しており、マイコン51、52とは別途に第1基板21に実装される。これにより、一部の回路部610、620に異常が生じた場合であっても、回転角θmおよび回転回数TCの演算を継続することができる。【選択図】 図9
