Product Description:

B&R Automation’s 8LSA35.E0030D100-0 electric unit is a three-phase synchronous motor in the 8LS Synchronous Motors series for general automation axis duties. The 8LSA designation indicates a standard build that omits reinforced bearings. Designed for flange mounting, the motor provides rotational power to servo drives where compact size and a prewired connector are important. Its role in industrial automation centers on precise position and velocity control with feedback delivered by an integrated optical encoder.

The performance envelope begins with a rated speed of 3000 rpm, which is the speed for continuous operation with a compatible inverter. Heat is removed through a self-cooling airflow path that relies on free circulation, eliminating external blowers and simplifying enclosure layouts. Position feedback is generated by an Optical EnDat encoder, allowing digital transmission of incremental and absolute data to B&R drives. Machine-side attachment uses a 91.3 mm square flange that aligns with common mounting interfaces, while power and feedback leads exit through an angled connection that can swivel to relieve cable strain in confined cabinets. The keyed shaft end delivers positive torque transfer to pulleys, couplings, or gear stages.

Control fidelity is enhanced by EnDat 2.1, which supports advanced diagnostics and compatibility with modern motion controllers. Dimensional planning is aided by length code 5, which identifies the stator stack size used for this motor without changing the flange footprint. The rotor is engineered without a holding brake, so static load retention must be supplied externally when power is removed. Feedback density reaches 13/0-bit single-turn resolution, which suits applications that home each cycle. The motor also has no oil seal, which reduces drag for high-speed duty, and it uses a standard bearing set instead of reinforced bearings.
