Serving as a servo-class actuator, it converts drive inverter current into controlled mechanical rotation for indexing tables, pick-and-place axes, and other precision motion in automated cells. The A-level configuration indicates a standard design without reinforced bearings, so it is intended for general-duty positioning tasks rather than high-radial-load spindle applications.\u003c\/p\u003e\u003cp\u003eElectrical and mechanical interfacing is simplified by a connector with an \u003cstrong\u003eangled swivel\u003c\/strong\u003e orientation, allowing cable clearance without tight bend radii. Cooling is provided by \u003cstrong\u003eself-cooling through free circulation\u003c\/strong\u003e, so ambient air removes heat without auxiliary fans or liquid jackets. Position feedback is supplied by an \u003cstrong\u003einductive EnDat\u003c\/strong\u003e encoder that uses the \u003cstrong\u003e2.2\u003c\/strong\u003e protocol, so the drive receives absolute position data with cyclic redundancy checking over a single pair. The \u003cstrong\u003e100 mm\u003c\/strong\u003e square mounting face meets IEC flange standards, and a keyed shaft couples directly to gearboxes. The built-in flange seats the motor securely, and the length code 4 stack balances torque output with limited overall depth. Because no oil seal is fitted, the front bearing should not face oil splash.\u003c\/p\u003e\u003cp\u003eA \u003cstrong\u003estandard holding brake\u003c\/strong\u003e generates static torque when power is removed, which helps hold vertical axes in place. Sustained rotor speed up to \u003cstrong\u003e4500 rpm\u003c\/strong\u003e supports quick indexing while maintaining controlled motion in repetitive cycles. Encoder resolution is given as \u003cstrong\u003e19\/12\u003c\/strong\u003e single-turn and multi-turn bits, allowing precise position feedback during slow moves. The encoder also provides \u003cstrong\u003emulti-turn capability for 4096 revolutions\u003c\/strong\u003e, preserving position information through multiple shaft turns after a power cycle, and position and brake status are communicated over the EnDat channel.\u003c\/p\u003e","brand":"B \u0026 R Automation","offers":[{"title":"Unused Surplus","offer_id":52056657527085,"sku":null,"price":10531.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0747\/7696\/9517\/files\/8lsa44db045d300-3__5d2445c3-5449-4d35-9ab9-8e6ca32870e0.webp?v=1778051823","url":"https:\/\/servosupplier.com\/products\/8lsa44db045d300-3","provider":"Servo Supplier","version":"1.0","type":"link"}
