8LSA44.D0030D000-3 by B & R Automation

The 8LSA44.D0030D000-3 is a three-phase synchronous motor manufactured by B&R Automation as part of the 8LS Synchronous Motors series. It acts as a rotary actuator for automated machinery and motion-control cells in industrial environments. It is intended for machine axes that need controlled rotation during indexing, synchronized transport, or repeatable positioning tasks. The motor has a smooth shaft end that transmits torque without a key. This layout suits friction-locked couplings instead of keyed hubs.

With a nominal shaft speed of 3000 rpm, the motor can track high-frequency command profiles. The housing uses self-cooling through free circulation, so no external blower is required. A 100 mm pilot circle seats the unit to gearboxes or frames, and the standard 8LSA configuration uses no reinforced bearing. Power and feedback leads enter through an angled swivel connector, which simplifies cable routing in compact cabinets, and the mating side is a molded industrial connector. The motor has no holding brake, so external mechanics must secure position during power-off events. The stator winding uses a three-phase synchronous design, so torque production remains linear with sinusoidal current and helps reduce speed ripple in servo loops. The motor does not have an oil seal, so lubricant must be kept away from the front bearing.

Feedback precision is delivered by an Optical EnDat encoder that communicates through the bidirectional 2.2 protocol version, allowing automatic parameter upload to the drive. The sensor provides 25/0 bits of coded resolution, which corresponds to single-turn data without a multi-turn count. Because the execution is single-turn, absolute position is reported within one mechanical revolution rather than across multiple shaft turns. Revision 3 keeps the same mounting flange and connector layout while using updated magnetic materials that do not alter external dimensions or shaft form.
