Product Description:
The 8LSA57.DB045S000-3 is produced by B&R Automation for the 8LS Synchronous Motors series. Designed for general-purpose motion axes in packaging, material-handling, and light machining equipment, the unit converts drive current into regulated angular displacement and torque. Its 8LSA designation indicates a standard build without reinforced bearings. The motor is supplied without a holding brake, making it suitable for systems that secure the load through external clamping or continuous drive torque.
At a rated speed of 4500 rpm, the rotor supports rapid travel without overshoot when paired with a compatible servo inverter. Power and feedback conductors share a single-cable solution, which shortens installation time and reduces electromagnetic coupling. Position data is generated by an inductive EnDat sensor that communicates through EnDat 2.2, allowing automatic electronic nameplate transfer and high-speed closed-loop control. The transducer provides 19/12 bits of single-turn and multi-turn resolution for precise positioning across the full mechanical range. Length code 7 indicates the active stack height, while product revision 3 identifies the current manufacturing update. A connector mounted on the rear housing provides the required electrical interface.
The flange pilot measures 142 mm in diameter, enabling direct attachment to compatible gearboxes or machine frames. An internal counter records up to 4096 revolutions of shaft travel, so absolute position remains available after a loss of power. Heat is removed by a self-cooling housing that relies on free air circulation, eliminating the need for forced ventilation in most installations. Output torque is delivered through a smooth shaft, simplifying coupling assembly and avoiding the stress concentrations associated with a keyway. The motor uses a mounting flange and standard bearings for stable installation. It has no oil seal, making it better suited to clean operating areas than applications requiring high-pressure washdown protection. The hybrid connector combines the necessary power and feedback connections at the rear of the housing.
