drive field weakening speed control is often used in hoisting mechanisms to improve operating efficiency. The basic idea is simple: the motor runs at the highest speed under no-load conditions, runs at rated speed under heavy load, and uses a calculated field weakening curve to determine the proper speed for loads between heavy load and no load. For overhead crane and gantry crane hoist drives, this helps increase lifting speed under no-load or light-load conditions, reduce hoisting time, shorten the working cycle, and improve equipment productivity. Some special applications must follow their own design data. For example, on a shipbuilding gantry crane, if the no-load, half-load, and full-load speeds [&hellip;]","protected":false},"featured_media":16297,"parent":0,"menu_order":0,"template":"single-SEO-Table.php","posts_category":[197],"posts_tag":[795],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hndfcrane.com\/ja\/wp-json\/wp\/v2\/xmxposts\/16285"}],"collection":[{"href":"https:\/\/www.hndfcrane.com\/ja\/wp-json\/wp\/v2\/xmxposts"}],"about":[{"href":"https:\/\/www.hndfcrane.com\/ja\/wp-json\/wp\/v2\/types\/posts"}],"version-history":[{"count":9,"href":"https:\/\/www.hndfcrane.com\/ja\/wp-json\/wp\/v2\/xmxposts\/16285\/revisions"}],"predecessor-version":[{"id":16300,"href":"https:\/\/www.hndfcrane.com\/ja\/wp-json\/wp\/v2\/xmxposts\/16285\/revisions\/16300"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.hndfcrane.com\/ja\/wp-json\/wp\/v2\/media\/16297"}],"wp:attachment":[{"href":"https:\/\/www.hndfcrane.com\/ja\/wp-json\/wp\/v2\/media?parent=16285"}],"wp:term":[{"taxonomy":"posts_category","embeddable":true,"href":"https:\/\/www.hndfcrane.com\/ja\/wp-json\/wp\/v2\/posts_category?post=16285"},{"taxonomy":"posts_tag","embeddable":true,"href":"https:\/\/www.hndfcrane.com\/ja\/wp-json\/wp\/v2\/posts_tag?post=16285"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
