8LSA25.D9060U049-3 by B & R Automation

The 8LSA25.D9060U049-3 is a three-phase synchronous motor produced by B & R Automation for the 8LS Synchronous Motors series. As a compact servo actuator, it converts electrical energy into controlled rotary motion for positioning or velocity tasks in automated machinery and gantry axes. The motor uses the 8LSA mechanical designation and is shipped with a mounting flange so it can be fixed directly to drive assemblies or gearboxes without auxiliary brackets. Its compact format suits motion axes where installation space is limited and stable rotary response is required.

The motor's maximum mechanical speed is 6000 rpm, giving integration flexibility in high-speed feed drives or spindle functions. Continuous operation uses self-cooling by free circulation, meaning heat is removed through natural airflow around the housing without forced fans. A mounting interface of 58 mm on the square flange complies with IEC size coding and simplifies interchange with other frame sizes. For position feedback, the unit incorporates Inductive EnDat sensing, and this non-contact encoder minimizes wear while providing absolute position data. The feedback channel provides a resolution of 19/12 bits for single-turn and multi-turn data, permitting fine interpolation for precise motion loops.

The digital interface follows EnDat version 2.2, enabling bidirectional parameter transfer and electronic nameplate functions when connected to B & R ACOPOS drives. Power and feedback lines are consolidated in a single connector, reducing wiring and assembly time while keeping the cable entry compact. Multi-turn capability extends to 4096 revs, allowing reliable homing after power loss without external batteries. The motor is cataloged under product revision 3, which identifies the documented product variant for this model. The combined power and feedback interface also reduces the number of separate cable runs on tightly packed machine axes.
