The device includes a multi-phase/two-phase transformation unit for converting a plurality of detection signals, each being outputted from rotation detectors in accordance with a rotation angle of a rotating body so as to output transformed signals as two-phase signals; an addition-subtraction calculation unit for generating addition-subtraction signals by mutually performing addition to the two-phase signals and subtraction therefrom; an amplitude correction unit for modifying amplitudes of the addition-subtraction signals in accordance with an amplitude correction value, and for outputting post-correction addition-subtraction signals; and an angle calculation unit for calculating an angle based on the post-correction addition-subtraction signals, and for outputting an angular signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotation angle detection device having increased accuracy","description":"A rotation angle detection device for accurately detecting a rotation angle is obtained even when electromagnetic noise due to an electrical component(s) and the like of an electric automotive vehicle","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11255703","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.
