A rectifying unit alternately turns on and off the switch to rectify the voltage at an output end of the stator winding, thus generating a rectified voltage. An excitation current supplying circuit is communicably connected to the modulation signal generator via a communication line, and starts a supply of an excitation current to the excitation winding of the rotor to induce a rotating magnetic field in the stator winding when the modulation signal output from the modulation signal generator is input thereto via the communication line."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotary electric machine capable of detecting malfunction in switch","description":"In a rotary electric machine, a modulation signal generator generates a modulation signal including information indicative of rotation of a rotor based on change of a voltage at an output end of a sta","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9716456","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.
