8LSC5B.E0030D100-3 by B & R Automation

The 8LSC5B.E0030D100-3 is an industrial servo motor produced by B&R Automation for the 8LS Synchronous Motors series. It serves as a drive element in automated axes, supplying controlled torque and speed to machinery that depends on precise electrical commutation. By integrating position feedback and direct mounting features, the unit suits material handling stations, packaging workcells, and light machining centers. It is intended for closed-loop motion systems in which the drive regulates current, speed, and position during repetitive machine cycles.

The motor is a three-phase synchronous machine with a rated speed of 3000 rpm, allowing operation with common inverter outputs. Heat is removed through a built-in fan assembly, so continuous-duty operation does not rely on external airflow. A 142 mm flange provides the mounting interface for rigid attachment to gearboxes or machine frames. Rotor position is detected by an Optical EnDat encoder that uses EnDat 2.1 communication, with 13-bit single-turn and multi-turn information for feedback. The shaft has a key for positive torque transfer, and the motor comes without a holding brake and without an oil seal. Any required load holding or shaft-end sealing must be provided elsewhere in the machine.

For mechanical integration, the cables leave the housing in an angled swivel orientation, which helps reduce sharp bends near the connection point. A sturdy mounting flange carries machine-side loads into the frame during installation. The encoder also provides single-turn position tracking for precise commutation within one mechanical revolution. One connector carries both power and feedback conductors, which keeps the motor interface compact. Revision 3 identifies the listed motor version, and the standard 8LSC configuration does not use reinforced bearings so the unit retains the compact B-length arrangement.
