Further provided is a method of driving a planar motor by using piezo driving legs, which implements three movement modes, i.e., a sliding mode, a walking mode, and a fine tuning mode. The sliding mode has the fastest speed of motion, the walking mode has a relatively slow speed of motion but has a high positioning accuracy and a high-accuracy tracking capability, and the fine tuning mode is used for the adjustment of the planar motor at a final position and has the highest positioning accuracy. The piezo-actuated planar motor of the present invention can effectively overcome the defects of a small movement range and a low speed in a conventional nano-positioning platform."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Piezo ceramic planar motor and driving method thereof","description":"Provided is a piezo-actuated planar motor, comprising a planar substrate and a mover installed on the planar substrate, the piezo-actuated planar motor further comprising: at least one piezo driving l","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10491140","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.
