A power supply provides power to an electrical circuit defined by one of the first and second windings to produce a magnetic flux in the yoke corresponding to the one of the first and second windings and defining an excitation yoke. A monitoring module provides a measurement of a characteristic of an electrical circuit defined by the other one of the first and second windings to identify a fault corresponding to an eddy current between individual laminations in the laminated core."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fault detection for laminated core","description":"A method and system for evaluating the condition of a laminated core of an electric machine, and including a first yoke wound with a first winding and having a first pair of arms spanning between a fi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8508220","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.
