It provides the rotary actuation required for positioning or speed-controlled axes, converting electrical power into mechanical torque for conveyors, pick-and-place gantries, and other automated machinery. When used with a compatible servo controller, it supports repeatable start-stop motion and stable speed regulation across changing loads. High rotational accuracy and compact dimensions make it suitable for tight installation spaces in modern industrial control systems.\u003c\/p\u003e\u003cp\u003eThe motor’s maximum mechanical velocity is \u003cstrong\u003e4500 rpm\u003c\/strong\u003e, allowing rapid traverse cycles without exceeding rotor stress limits. A flange diameter of \u003cstrong\u003e142 mm\u003c\/strong\u003e provides a stable interface for precise alignment to gearboxes or direct-drive loads. Internal heat is removed by \u003cstrong\u003eself-cooling through free circulation\u003c\/strong\u003e, so no auxiliary fan or liquid circuit is required as long as ambient air can move around the housing. Cables exit through an \u003cstrong\u003eangled swivel\u003c\/strong\u003e port, and the factory-installed \u003cstrong\u003econnector\u003c\/strong\u003e eliminates open-lead terminations. The motor does not include an oil seal, so the shaft interface should be protected from contaminant splash, and the mounting flange with length code 7 sets the overall stack height and envelope.\u003c\/p\u003e\u003cp\u003eA \u003cstrong\u003estandard holding brake\u003c\/strong\u003e clamps the rotor when the inverter disables torque, helping the axis remain in position at standstill. Power transmission relies on a \u003cstrong\u003esmooth shaft\u003c\/strong\u003e, which supports clamp or shrink-fit couplings without a keyway. The 8LSA configuration uses \u003cstrong\u003eno reinforced bearing\u003c\/strong\u003e, so radial load capability matches typical servo duty rather than heavy pulley service. Its \u003cstrong\u003ethree-phase synchronous\u003c\/strong\u003e electromagnetic construction supports constant torque production per electrical cycle, enabling tight speed regulation when paired with compatible B\u0026amp;R ACOPOS drives.\u003c\/p\u003e","brand":"B \u0026 R Automation","offers":[{"title":"Refurbished","offer_id":52056658673965,"sku":null,"price":1871.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/8lsa57e3045d200-0__27d11e59-3c88-442f-9395-361430dd47f3.webp?v=1778051867","url":"https:\/\/servosupplier.com\/products\/8lsa57e3045d200-0","provider":"Servo Supplier","version":"1.0","type":"link"}
