8LSN57.EA022D100-0

The B & R Automation 8LSN57.EA022D100-0 servo motor from the 8LS Synchronous Motors series delivers robust performance for demanding industrial automation environments. This three-phase synchronous motor features a compact Frame Size 57 with a flange diameter of Flange Dimension 142 mm, providing a balanced power-to-size ratio. With a Rated Voltage 400 V supply and a Rated Speed 2200 rpm output, the 8LSN57.EA022D100-0 is engineered for precision motion control. The design incorporates a Designation 8LSN self-cooling system with increased mass moment of inertia to ensure stable thermal characteristics during continuous operation. Engineered to meet the strict requirements of automated production lines, this motor combines durability and accuracy in one package.

The motor’s technical configuration follows a Standard Configuration that simplifies integration into modular drives and controllers. It employs Inductive EnDat encoder technology with EnDat Version 2.1, offering high-resolution position feedback for precise closed-loop control. Electrical parameters include a Nominal Current 7.4 A under rated load and a Maximum Current 8.8 A during peak torque events. The unit’s Product Revision 0 and Length Code 7 specify its exact mechanical footprint, while the Connection Direction Angled (swivel) connector channel streamlines cable routing in tight installations. The shaft is supplied With key to interface securely with standard couplings, ensuring reliable torque transmission across varying load conditions.

Operational performance is enhanced by the motor’s IP65 degree of protection, safeguarding internal components from dust ingress and low-pressure water jets. The Self-cooling, increased mass moment of inertia cooling principle maintains stable operating temperatures without external fans, reducing maintenance and enhancing service life. A peak torque margin ensures smooth acceleration up to the Rated Speed 2200 rpm, and consistent torque delivery of 7.75 Nm across the operating range. The robust construction withstands industrial vibration and thermal cycling, promoting consistent performance in packaging, assembly, and material handling systems.

System integration is streamlined for B&R Automation’s X20 and X67 drive platforms, supporting direct-drive applications and multi-axis synchronization. The 8LSN57.EA022D100-0 is ideal for robotics, pick-and-place systems, and conveyor dynamics where precise speed and position control are critical. Its angled swivel connector and compact form factor reduce cabinet space requirements, accelerating machine layout and commissioning. Overall, this motor addresses the needs of high-throughput manufacturing and flexible automation cells, delivering reliable motion control in diverse industrial applications.
