{"product_id":"8lsa57e1045d000-0","title":"8LSA57.E1045D000-0","description":"\u003cp\u003eB \u0026amp; R Automation manufactures the \u003cstrong\u003e8LSA57.E1045D000-0\u003c\/strong\u003e, a three-phase synchronous motor in the 8LS Synchronous Motors series. The unit carries the 8LSA designation and belongs to the standard performance class for servo axes. Designed for positioning and velocity control in industrial automation, it converts electrical power into rotational motion with high dynamic accuracy. This motor is used in pick-and-place gantries, packaging lines, and indexing tables where responsive torque and compact dimensions are required.\u003c\/p\u003e\u003cp\u003eThe motor delivers a nominal speed of \u003cstrong\u003e4500 rpm\u003c\/strong\u003e, allowing fast cycle times on high-speed axes. Thermal management relies on \u003cstrong\u003eself-cooling with free circulation\u003c\/strong\u003e, so no external fan or liquid circuit is required. Power and feedback conductors exit the housing through an \u003cstrong\u003eangled swivel connector\u003c\/strong\u003e, which helps with cable routing in tight spaces. Integration to machine frames is provided by a mounting flange with a face diameter of \u003cstrong\u003e142 mm\u003c\/strong\u003e. The motor uses a single industrial connector, and the length-code 7 housing fits mid-range torque classes within the series. It does not include a holding brake or an oil seal, so external provisions may be needed for back-driving, vertical loads, or protection against lubricant ingress.\u003c\/p\u003e\u003cp\u003eThe feedback system uses an \u003cstrong\u003eoptical EnDat encoder\u003c\/strong\u003e with version 2.1 protocol for fully digital position reporting. It supports a native resolution of \u003cstrong\u003e13\/12-bit\u003c\/strong\u003e for single-turn and multi-turn tracking, and the built-in counter adds \u003cstrong\u003emulti-turn capability of 4096 revolutions\u003c\/strong\u003e so absolute position can be retained after power loss. A \u003cstrong\u003esmooth shaft\u003c\/strong\u003e simplifies coupling to precision gearheads or direct-drive loads where keyways are unnecessary. The mechanical build follows a \u003cstrong\u003estandard configuration without reinforced bearings\u003c\/strong\u003e, which is suitable for radial loads within the normal catalog limits.\u003c\/p\u003e","brand":"B \u0026 R Automation","offers":[{"title":"Unused Surplus","offer_id":52056657297709,"sku":null,"price":9969.98,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":52086967664941,"sku":null,"price":6718.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/8lsa57e1045d000-0__6a6786d9-1f02-4d3b-89b2-9aee4fd0195d.webp?v=1778051809","url":"https:\/\/servosupplier.com\/products\/8lsa57e1045d000-0","provider":"Servo Supplier","version":"1.0","type":"link"}
