Product Description:

B&R Automation manufactures the 8LS Synchronous Motors series for servo axes that need compact torque density and integrated feedback. The 8LSA5A.DB022S000-3 is a three-phase synchronous motor identified by the 8LSA designation, which marks a standard build without reinforced bearings. It is assembled in the A length code and issued as product revision 3, so its overall depth and electrical parameters correspond to that revision level. In industrial automation, it generates precise rotary motion for tool tables, gantry drives, and feeder modules that rely on high positional repeatability and quick acceleration. This motor format is well suited to applications that need accurate motion control without adding unnecessary installation bulk.

The mechanical interface follows a flange-mount pattern with a flange diameter of 142 mm. At the shaft, the motor reaches a rated speed of 2200 rpm, allowing direct coupling to moderate-ratio gearboxes or belt stages. Thermal management uses a self-cooling principle with free air circulation, so no external blower or liquid circuit is required. Position data are produced by an inductive EnDat encoder that works with EnDat version 2.2. The sensor provides a high-resolution digital word of 19/12 bits for single-turn and multi-turn counting, which supports stable velocity regulation and accurate position tracking at low speed.

For simplified wiring, the stator uses a single-cable solution in hybrid form, carrying power and serial feedback through one connector interface. The mating hardware is a sealed circular connector, and the output shaft is a smooth shaft suited to clamp or keyless couplings. Absolute position is maintained over 4096 revs of the mechanical turn counter, and the housing fastens to machinery through a mounting flange. The motor is supplied without a holding brake and without an oil seal, so external measures are needed when static load retention or lubricant separation is required. This arrangement can help reduce cable routing complexity while keeping the mechanical connection straightforward.
