8LSA25.E5060D200-0 by B & R Automation

8LSA25.E5060D200-0 is a three-phase synchronous motor produced by B&R Automation within the 8LS Synchronous Motors series. As a synchronous motor, it converts commanded electrical power into controlled rotary motion for servo-driven equipment. The model code begins with the 8LSA designation, indicating a standard build without a reinforced bearing, and it uses length code 5. An integrated mounting flange allows the unit to fasten directly to machine frames in packaging, printing, or general motion axes where compact, high-speed rotary positioning is required.

The motor reaches a rated speed of 6000 rpm, allowing short cycle times for indexing drives. A flange dimension of 58 mm sets the interface envelope for gearboxes or couplings, while the self-cooling, free circulation design removes heat without external blowers. Power and feedback are routed through a connector with an angled swivel orientation to ease cable routing in tight cabinets. The output uses a smooth shaft, which is suitable for clamp hubs or friction couplings. Because an oil seal is not present, the machine side must provide its own contamination barrier, and the compact connection layout helps where cable clearance is limited.

An optical EnDat encoder compliant with version 2.1 supplies absolute position data for closed-loop motion control. Its raw resolution is 13/12 bits for single-turn and multi-turn counting, and the multi-turn system tracks up to 4096 revs without losing reference. Absolute feedback lets the drive retain position information after a power cycle, which reduces the need for a reference move at startup. When power is removed, a standard holding brake locks the rotor to hold load position on vertical or static axes. The EnDat 2.1 signal shares the same connector used for power, which reduces wiring and supports automatic parameter detection in compatible B&R servo drives.
