8LSA44.E3030D200-0 by B & R Automation

B&R Automation manufactures the 8LSA44.E3030D200-0 in the 8LS Synchronous Motors series. The 8LSA code indicates a standard build without reinforced bearings. Designed for industrial automation, the motor converts three-phase supply power into regulated torque so positioning and speed-controlled axes can maintain repeatable motion profiles under servo drive supervision. This layout suits machinery that depends on stable acceleration and accurate speed regulation during continuous operation.

The motor has a rated speed of 3000 rpm, allowing control loops to respond quickly while remaining within thermal limits. A square flange dimension of 100 mm provides a centering shoulder for direct coupling to gearboxes or machine frames. Power and feedback leads exit through an angled swivel connector housing, which helps reduce cable strain in tight or hinged installations. Heat is removed by self-cooling through free air circulation, so the housing dissipates losses without forced airflow. For vertical or loaded shafts, the motor includes a standard holding brake so the load can remain stationary when drive power is removed. Length code 4 indicates the active stack height and supports the motor's continuous torque capability.

The motor has a smooth shaft, which eases coupling with clamping hubs and avoids keyway stress concentrations. However, there is no shaft seal, so external sealing is necessary in lubricated environments. The housing mounts through a mounting flange, supporting rigid alignment without additional feet. Internally, it uses a three-phase synchronous design, so the stator produces flux linkage that stays synchronized with inverter frequency for accurate positioning. A single circular connector carries phase, brake, and sensor lines, which keeps cabling compact and limits enclosure penetrations to one interface.
