Product Description:

The 8LSA25.D9030S200-3 is a three-phase synchronous motor manufactured by B & R Automation as part of the 8LS Synchronous Motors series. Designed for servo axes in packaging, handling, and processing lines, it converts electrical energy into precisely regulated rotational motion. The internal code 8LSA indicates a standard mechanical configuration that omits reinforced bearings, and the length code 5 indicates the axial stack required for its power class. A mounting flange is integrated so the housing can bolt directly to machine frames without additional brackets, simplifying installation in tight automation spaces. This layout suits compact servo installations where direct mounting and predictable alignment are important.

At its nominal operating point, the rotor reaches 3000 rpm, a speed that matches the frequency output of typical B & R servo drives and supports the mechanical throughput of the axis. The front face follows a 58 mm square flange pattern, allowing alignment with standard planetary gearheads. Power, feedback, and brake supply are routed through a single-cable solution, minimizing wiring space and using a keyed connector at the motor shell. Heat is removed by self-cooling, meaning the housing relies on free air circulation and needs no auxiliary fan. Position data are delivered by the integrated Inductive EnDat encoder, which maintains absolute angle information even during high-duty cycles. The smooth shaft eases press-fit coupling, no oil seal is fitted, and product revision 3 reflects incremental electrical optimizations.

The feedback chain complies with 2.2 EnDat protocol, enabling bidirectional parameter exchange between the drive and sensor. Within this framework, the encoder provides 19/12 bits of single-turn and multi-turn resolution, and it can track up to 4096 revs without loss of position after power-down. This arrangement lets the axis retain position information after shutdown and return to controlled motion without a separate reference search. A standard holding brake is mounted on the rear, supplying static torque to lock the axis during emergency stops or when mains power is disconnected.
