The rotation detection sensor detects a rotation reference position with the detection of switching from projections to a missing tooth part on the basis of a gap to the signal rotor, and detects switching from the missing tooth part to the projections to output a rotation reference position signal indicative of position information on the rotation reference position at timing of the detection. An ECU receives the detection signal and the rotation reference position signal from the rotation detection sensor, and acquires the rotation reference position on the basis of the rotation reference position signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotation detector","description":"A rotation detection sensor is disposed to face an outer peripheral part of a signal rotor, and outputs a detection signal corresponding to a position of the outer peripheral part with the rotation of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9797747","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
