The 8LSA designation indicates the standard configuration without a reinforced bearing, making the motor suitable for medium-duty positioning tasks in automated assembly and material-handling machinery. In automation systems, it serves as the rotary output element for indexing axes, transfer units, and similar motion points that require controlled acceleration and deceleration. It delivers closed-loop torque and speed so that motion controllers can hold position or follow dynamic motion profiles with repeatable accuracy.\u003c\/p\u003e\u003cp\u003eAt its nominal operating point, the motor reaches \u003cstrong\u003e3000 rpm\u003c\/strong\u003e. As a \u003cstrong\u003ethree-phase synchronous\u003c\/strong\u003e motor, its rotor speed follows the frequency commanded by the drive. Heat is removed by \u003cstrong\u003eself-cooling with free circulation\u003c\/strong\u003e, so no external fan or liquid circuit is required. This cooling method avoids separate blower hardware and supports compact machine layouts. The IEC square mounting flange measures \u003cstrong\u003e100 mm\u003c\/strong\u003e, and the power and feedback connections use an \u003cstrong\u003eangled swivel\u003c\/strong\u003e layout that helps route cables in tight spaces. Electrical termination is provided through a \u003cstrong\u003econnector\u003c\/strong\u003e interface. Length code 5 indicates a medium stator stack that balances torque output and rotor inertia for general servo duty. The keyed shaft end transmits torque positively, but the motor does not include an oil seal, so the shaft area should be protected from lubricant contamination.\u003c\/p\u003e\u003cp\u003eThe inductive EnDat sensor provides absolute feedback with a resolution of \u003cstrong\u003e19\/0 bits\u003c\/strong\u003e, which means it supplies 19-bit single-turn data and no multi-turn count. It communicates through protocol version \u003cstrong\u003e2.1\u003c\/strong\u003e. Because the encoder is \u003cstrong\u003esingle-turn\u003c\/strong\u003e, the controller receives position data for one mechanical revolution, which suits axes that reference home regularly during operation. No holding brake is installed, so static loads must be restrained by the drive or by external mechanics during power loss. The unit is product revision 3.\u003c\/p\u003e","brand":"B \u0026 R Automation","offers":[{"title":"Unused Surplus","offer_id":52056657101101,"sku":null,"price":9564.3,"currency_code":"USD","in_stock":true},{"title":"Refurbished","offer_id":52144248193325,"sku":null,"price":8694.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/8lsa45ea030d100-3__72750602-47a2-4d47-bd59-961213d0f919.webp?v=1778051797","url":"https:\/\/servosupplier.com\/products\/8lsa45ea030d100-3","provider":"Servo Supplier","version":"1.0","type":"link"}
