The data storage device further comprises control circuitry comprising a spindle motor driver comprising a plurality of switches including a first switch and a second switch configured to commutate the windings. A current flowing through the first switch is measured for a first part of an electrical cycle of the spindle motor. The measured current is processed to generate an estimated current flowing through the second switch during a second part of the electrical cycle of the spindle motor, wherein the first part of the electrical cycle is different from the second part of the electrical cycle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage device adaptively estimating spindle motor current","description":"A data storage device is disclosed comprising a head actuated over a disk and a spindle motor configured to rotate the disk, wherein the spindle motor comprises a stator, a rotor, and a plurality of w","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9666224","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.
