The two signals are produced from two elements located at positions farthest in a rotational angle of the rotor among plural rotation detecting elements located at positions different from each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotation detector and rotation detection method","description":"A rotation detector detecting rotation of a rotor, based on a signal produced according to rotation of the rotor, having a waveform according to a rotational cycle thereof, includes a signal obtaining","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9742425","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.
