8LSN55.EB030D000-0 by B & R Automation

The 8LSN55.EB030D000-0 belongs to the 8LS Synchronous Motors series manufactured by B&R Automation. This three-phase synchronous motor is used as a torque source in positioning axes, pick-and-place arms, and other motion platforms that require precise electronic commutation in packaging, assembly, and handling equipment. A mounting flange allows direct attachment to machine frames, which supports compact installation in automated equipment. The 8LSN designation identifies the increased-inertia variant in the series, making it suitable for applications that benefit from steadier motion under changing loads.

Its rated speed of 3000 rpm sets the nominal operating speed when the motor is paired with a matched inverter. Position data are supplied through an inductive EnDat encoder that communicates over EnDat version 2.1, allowing absolute position transfer and electronic nameplate functions. Internal interpolation provides a resolution of 19/12 bits for single-turn and multi-turn data, so the drive can detect fine position changes without additional sensors. A flange dimension of 142 mm supports face mounting and matches common gearbox interfaces. Length code 5 indicates the stator stack depth, and the motor is built without a holding brake or oil seal, which helps keep the overall length shorter.

Connection hardware exits the housing through an angled swivel conduit box, which helps route cables where clearance is limited. The swivel outlet also helps reduce sharp cable bends near the housing. Cooling is handled by self-cooling, so the motor dissipates heat without external fans or separate airflow equipment. A smooth shaft supports coupling to backlash-free clamping hubs often used in precision motion systems. The multi-turn encoder can track up to 4096 revs, preserving absolute position information after power loss within the encoder's counting range.
