8LSA57.DB045S000-3

The B & R Automation 8LSA57.DB045S000-3 is a precision three-phase synchronous servo motor in the acclaimed 8LS Synchronous Motors series, engineered for demanding industrial automation tasks. With a compact 57 mm frame size and a square 70 mm flange dimension, this motor delivers a rated power of 750 W at 230 V input, achieving a rated speed of 3000 rpm and a rated torque of 2.4 Nm. It features a stall torque of 2.7 Nm for stable performance under variable load conditions. The design incorporates an inductive EnDat encoder with a resolution of 19/12 (single/multi-turn bits) for high-precision position feedback. Configured with a length code of 7 and product revision 3, the motor maintains a low profile while housing advanced functionality.

Performance is optimized through a hybrid single-cable connection direction that combines power and feedback in one harness, reducing wiring complexity. The internal grooved ball bearings, sealed and greased, ensure long service life and minimal maintenance, while the natural convection cooling preserves efficiency without active fans. The motor’s electrical characteristics are enhanced by the absence of a holding brake, in line with the 8LSA standard configuration summary that prioritizes compactness and reliability. The integrated parameter chip automatically communicates motor-specific data to B&R servo drives, enabling auto-configuration and rapid commissioning. This synergy delivers smooth, constant rotation across all four pole pairs, with minimal torque ripple and precise dynamic response.

Built to withstand harsh conditions, the 8LSA57.DB045S000-3 carries an IP65 protection class, guaranteeing dust-tight performance and resistance to water jets. The mounting flange availability and robust frame allow straightforward integration into existing machine architectures, while the swivel connector enhances wiring flexibility in confined control cabinets. Its three-phase synchronous motor type provides high torque density and energy efficiency, making it ideal for robotics, CNC machining, packaging, and light to medium-duty industrial automation applications. The combination of advanced encoder technology, compact footprint, and sealed bearing system ensures reliable operation and consistent throughput, minimizing downtime and maintenance costs.
