8LSA55.DB030S200-3 by B & R Automation

B&R Automation's 8LSA55.DB030S200-3 belongs to the 8LS Synchronous Motors series and serves as a three-phase drive motor for positioning and speed-controlled axes in automated machinery. The 8LSA designation identifies its configuration within the series, and the standard build omits a reinforced bearing, making it better suited to medium radial loads than extreme belt tension. Within an installation, the motor converts inverter output into mechanical rotation and supplies continuous torque to gantries, feeders, or packaging equipment.

The motor is a three-phase synchronous type and reaches a rated speed of 3000 rpm, allowing direct coupling to fast-moving loads without additional gearing. It has a flange dimension of 142 mm for the mounting interface, and a smooth shaft permits backlash-free clamp couplings. Feedback is generated by an Inductive EnDat encoder that supplies absolute position data with 19 single-turn bits and 12 multi-turn bits of resolution. Power, brake, and feedback lines exit through a single-cable hybrid solution, which reduces cabinet wiring and simplifies conduit routing. A standard holding brake engages automatically when power is removed to keep the load stationary.

Cooling is provided by self-cooling with free circulation, so no external blower is required when ambient airflow is available. Encoder communication complies with EnDat 2.2, enabling digital diagnostics on modern servo drives. The motor is Product Revision 3 and has length code 5, which refers to the active stack height inside the stator. Multi-turn tracking spans 4096 revs, which allows position retention after power loss. Connection is made through a keyed industrial connector, and the motor seats against the machine frame with a mounting flange. An oil seal is not present, so the shaft area should remain free of pressurized lubricant.
