8LSA55.E3045D000-0

The 8LSA55.E3045D000-0 by B & R Automation is a precision-engineered servo motor in the 8LS Synchronous Motors series, designed to excel in demanding industrial automation environments. It features a rated power of 300 W and achieves a rated speed of 4500 rpm, enabling rapid, accurate motion control. The motor delivers a rated torque of 9.5 Nm at nominal speed and offers a peak torque of 41.4 Nm for transient loads. A multi-turn absolute encoder provides precise position feedback and eliminates the need for homing, ensuring consistent performance in synchronized multi-axis systems. Its flange dimension of 142 mm and compatibility with standard mounting flange configurations allow straightforward integration into existing machine frameworks.

The 8LSA55.E3045D000-0 is built around a robust three-phase synchronous motor topology that combines high efficiency and reliable operation. A rated voltage of 320 V and rated current of 8.7 A balance power density with thermal stability, while the motor’s self-cooling, free circulation design uses natural convection to maintain safe operating temperatures. The configuration summary (8LSA: Standard, no reinforced bearing) ensures predictable dynamic behavior, and the length code of 5 highlights its compact axial footprint for space-constrained installations. The motor’s connection direction angled (swivel) simplifies cable routing in tight assemblies, and the absence of an oil seal removes a potential maintenance failure point.

Operational benefits include seamless heat dissipation through its cooling principle of unrestricted air flow, which removes the need for external fans or liquid cooling loops. The efficient electromechanical design minimizes losses, reducing overall energy consumption during continuous duty cycles. With a product revision 0 baseline, the motor offers consistent specs across production batches, aiding design standardization and simplifying spare parts management. The high peak torque of 41.4 Nm ensures the motor can handle short-duration overloads without derating, while the integrated encoder preserves absolute position data even during power interruptions. These features contribute to reduced downtime and lower total cost of ownership in automated machinery.

Integration into motion control architectures is streamlined by the motor’s standard mounting interfaces and encoder compatibility with common B & R Automation drive controllers. Its flange dimension of 142 mm aligns with industry norms, enabling drop-in replacement in legacy systems. Ideal applications span packaging machinery, robotic arms, CNC equipment, and high-speed conveyors where precise velocity and torque regulation are critical. The 8LSA55.E3045D000-0’s blend of performance, compactness, and self-cooling operation makes it a versatile solution for modern industrial automation challenges.
