8LCN58.EB030D030-0 by B & R Automation

The 8LCN58.EB030D030-0 is a synchronous servo motor built by B&R Automation and assigned to the 8LS Synchronous Motors series. As a torque-dense rotary actuator, it converts electrical energy into controlled mechanical motion for conveyors, indexing tables, and other closed-loop axes used in industrial automation cells. The motor integrates with the ACOPOS drive platform for high-precision positioning while maintaining a compact form factor for modern machinery. Its compact housing also helps it fit into machine sections where installation space is limited.

Mechanical attachment is handled through a mounting flange, and the mating face follows a 142 mm square geometry that aligns with standard machine frames. Power and feedback conductors exit through an angled swivel connector so cable loops can be relieved without adding bend stress. The motor uses self-cooling, so no external fan is required, and it has an increased mass moment of inertia. The rotor reaches a rated speed of 3000 rpm, and the smooth shaft end simplifies coupling to gearboxes or other driven components. Feedback is supplied by an inductive EnDat encoder, whose inductive scanning head resists contamination. Because the unit ships without a holding brake or oil seal, external restraints are needed and splash fluids should be avoided. Length code 8 identifies the stack height within the 58 frame.

Position data is delivered at 19/12 bits for single-turn and multi-turn measurement, enabling fine interpolation of each mechanical revolution. Protocol version 2.1 adds advanced diagnostics and automatic parameter upload to the drive. Absolute position is maintained across power cycles because the encoder tracks up to multi-turn (4096 revs), so the axis does not require a homing move after shutdown. The feedback format supports applications that need repeatable positioning after planned or unplanned power loss.
