8LSA44.EB030D200-0 by B & R Automation

The B & R Automation 8LSA44.EB030D200-0 is a three-phase synchronous motor in the 8LS Synchronous Motors series. The unit serves as a torque-generating element for precise speed and position control in automated packaging stations, gantry axes, and material-handling cells. It converts supplied three-phase power into regulated mechanical rotation, enabling closed-loop motion when paired with a compatible servo drive and encoder interface.

At a rated speed of 3000 rpm, the rotor maintains consistent velocity for applications designed around standard servo performance ranges. Position feedback is produced by an Inductive EnDat sensor operating on protocol version 2.1, which transmits absolute data to the controller. The encoder furnishes 19/12 bits of single-turn and multi-turn resolution, while its internal counter records up to 4096 revs so machine homing is unnecessary after power loss. Length code 4 keeps the stator stack moderate, and the 8LSA configuration denotes standard bearings without reinforcement for loads that stay within normal radial limits. A smooth shaft end facilitates press-fit couplings, and the motor is supplied without an oil seal, an arrangement suited to enclosures that already control lubricant migration. Connection hardware is a keyed connector that mates quickly during service.

Mechanical attachment is through a 100 mm square mounting flange that aligns directly to gearboxes or machine plates. A standard holding brake locks the shaft whenever the drive is disabled, preventing unwanted motion on vertical or indexing axes. Heat removal relies on self-cooling free-air circulation, eliminating external blowers and preserving compactness. Power and feedback conductors exit via an angled swivel connection, providing cable relief in tight cabinets and matching the specified swivel orientation.
