Product Description:

The 8LSA54.EB022D200-3 is a three-phase synchronous servo motor produced by B&R Automation for the 8LS Synchronous Motors series. Within automated assembly lines, packaging stations, or gantry axes, this motor converts electrical energy into precisely controlled rotary motion that can be indexed, positioned, or speed regulated by a matching drive controller. The 8LSA configuration indicates a standard build without reinforced bearings, making it suitable for dynamic yet moderate radial loads often encountered in general machinery.

A mounting flange sized at 142 mm forms the mechanical interface and allows direct bolting to gearboxes or frames while keeping axial runout low. Under continuous duty, the rotor can spin at 2200 rpm, a speed suited to moderate-torque motion tasks such as indexing tables or feeder rolls. Position information is supplied by an Inductive EnDat encoder that communicates through the 2.1 protocol, delivering absolute multi-turn data and eliminating manual homing. Thermal management relies on self-cooling through free air circulation, so only ambient airflow is required for rated operation. For static safety, a standard holding brake clamps the shaft when power is removed, preventing unwanted drift on vertical or suspended axes.

Electrical wiring exits the housing through an angled swivel connector, a layout that simplifies routing in tight panels and supports quick cable exchange. Feedback granularity reaches 19/12 bits for single-turn and multi-turn counts, and the internal counter supports up to 4096 revolutions so absolute position is retained across power cycles. Because the design has no oil seal, installations with splash exposure should use external shaft protection, and the smooth shaft end remains suitable for clamp collars or friction-lock couplings. The motor uses length code 4 and is product revision 3.
