Product Description:

The 8LSA35.EB060D000-0 is an AC servo unit produced by B&R Automation as part of the 8LS Synchronous Motors series. Designed for positioning and speed-regulated tasks in automated machinery, it fits applications that favor compact form factors over heavy bearing reinforcement. The internal 8LSA designation identifies a standard mechanical build that omits reinforced bearings yet supports precise motion control in conveyor sections, pick-and-place arms, and packaging axes. Its compact format also suits machine layouts where short installation depth and accurate servo response are more important than increased external load capacity.

Rated output speed reaches 6000 rpm, and thermal stability is preserved through a self-cooling airflow path that circulates freely around the stator without auxiliary fans. Rotor position is captured by an Inductive EnDat sensor that exchanges absolute values using protocol version 2.1. Because the motor is a three-phase synchronous design, its electromagnetic field synchronizes directly with drive frequency to deliver consistent torque across the speed range. Mechanical attachment is handled by a mounting flange that mates to the machine frame, while length code 5 corresponds to the stack height used for this model. Power and feedback conductors exit through an angled swivel outlet that accepts a coded connector, which helps keep cable routing compact in tight enclosures and reduces sharp cable bends near the housing. The unit is supplied without a holding brake and without an oil seal, allowing free back-driving when the axis must be moved without motor torque.

Absolute position data are delivered with 19/12 bits of single-turn and multi-turn resolution, giving the controller fine interpolation at slow speeds. The flange outer face measures 91.3 mm, a dimension that aligns with common gearbox inputs while keeping the overall diameter modest. A smooth shaft end eases coupling to clamped hubs and helps avoid the fretting that can occur around keyed connections. The encoder also tracks up to 4096 revs of multi-turn travel, so the control system can retain position information after power cycles without requiring a homing sequence. This feedback arrangement supports stable startup behavior and repeatable low-speed positioning in machines that need immediate position availability.
