8LSA53.DB030S800-3
The B & R Automation 8LSA53.DB030S800-3 servo motor is a high-performance member of the 8LS Synchronous Motors series, delivering 800 W of rated power at 230 V. This three-phase synchronous motor achieves a rated speed of 3000 rpm and combines seamlessly with standard grid frequency, simplifying drive configuration for industrial automation. Equipped with a digital absolute encoder based on Inductive EnDat technology, it provides Multi-turn (4096 revs) position feedback for precise motion control. The IP65-rated enclosure ensures robust protection against dust and water jets, making it suitable for washdown environments and harsh factory floors.
Detailed technical specifications include a flange dimension of 142 mm and a keyed shaft design for secure mechanical coupling under high torque demands. The motor features 4 pole pairs (8 poles total) optimized for synchronous operation, offering a stall torque of 12.5 Nm for brief high-load starts without drive intervention. Cooling is handled by a self-cooling, free circulation principle, eliminating the need for auxiliary blowers, and an integrated oil seal protects internal bearings. The standard holding brake provides reliable torque retention at standstill, while the connection type: plug connector simplifies installation and reduces wiring errors. Each unit is identified as Product Revision 3 with a length code of 3, and features a configuration summary marked as 8LSA: Standard, no reinforced bearing.
Operational performance is enhanced by a lightweight design weighing Approx. 5.5 kg, which minimizes support-structure demands and facilitates integration into compact systems. Natural cooling maintains thermal stability during moderate-duty processes, supporting consistent throughput under varying loads. The motor’s rated speed of 3000 rpm and precise multi-turn feedback enable dynamic acceleration profiles, making it ideal for pick-and-place robotics and CNC lathe spindle applications. The combination of keyed shaft, pole pair optimization, and robust brake ensures reliable operation in packaging machinery, where fast cycle times and accurate positioning are critical.
System integration is straightforward across industrial automation platforms due to its standard three-phase synchronous interface and single-cable topology for power and feedback. The IP65 protection class and holding brake option align with stringent safety and reliability requirements in automotive assembly lines and food and beverage production. As a part of the 8LS series by B & R Automation, the 8LSA53.DB030S800-3 excels in applications demanding precision, robustness, and ease of installation.
