8LSA36.E1030D900-3 by B & R Automation

B & R Automation manufactures the 8LSA36.E1030D900-3 three-phase synchronous motor for the 8LS Synchronous Motors series. The device is used as a drive source on positioning tables, pick-and-place arms, and similar automated stations where closed-loop motion is required. By combining magnetic torque production with an integrated feedback system, it supplies the precise speed and torque control needed in industrial automation. This arrangement supports repeatable motion on axes that must accelerate, decelerate, and settle accurately during each operating cycle.

The internal designation 8LSA indicates a standard build without reinforced bearings, and length code 6 indicates the active stator stack depth. A rated speed of 3000 rpm lets the shaft match common servo drive output frequencies, while thermal management uses self-cooling through free circulation so no external blower or liquid circuit is needed. The mounting flange has a face dimension of 91.3 mm, and an angled swivel connector helps simplify cable routing in tight cabinets. Power and feedback conductors terminate on an industry plug-in connector, and a keyed shaft end transfers torque to pulleys or couplings. A standard holding brake maintains position during power loss, and an oil seal helps prevent lubricant migration along the shaft.

Position data come from an optical EnDat encoder that communicates over EnDat 2.1 for digital bidirectional exchange with the drive. The sensor resolves mechanical angle to 13/12 bits in single-turn and multi-turn operation, and it stores absolute position across up to 4096 multi-turn revolutions, which reduces the need for a homing cycle after shutdown. Product revision 3 corresponds to this feedback arrangement. The connector hardware also supports service access without disturbing the motor mounting.
