Product Description:

The 8LSA35.DB030S100-3 is a three-phase synchronous motor produced by B & R Automation for its 8LS Synchronous Motors series. As a rotary servo element, it couples directly to machinery where consistent torque, rapid acceleration, and precise feedback are required. The motor integrates readily with B & R inverters and PLCs, allowing closed-loop speed or position control inside automated filling lines, gantries, or indexing stations. In such installations, it converts inverter power into mechanical motion without external gearing when load characteristics permit, which helps simplify machine layouts.

The mechanical output is rated for 3000 rpm, a speed that matches common conveyor and spindle requirements while staying within the thermal limits of its self-ventilated frame. Rotor position is captured by an Inductive EnDat feedback system that uses the 2.2 protocol, so the drive obtains absolute data immediately after power-up without homing moves. Power, signal, and brake lines share a single-cable solution, reducing cabinet wiring and minimizing connector count. Integration with a mounting flange measuring 91.3 mm across the pilot circle supports compatibility with IEC size 90 gearboxes and simplifies concentric alignment on machine frames.

The internal build follows the 8LSA standard, meaning no reinforced bearing is fitted and the overall length follows code 5 for compact enclosures. Multiturn tracking reaches 4096 revs, and position words carry 19/12 bits of single-turn and multi-turn detail for fine incremental control. This unit is identified as Revision 3, signaling updated electronics while retaining the earlier mechanical interface. A keyed shaft, connector termination, and the lack of an oil seal or holding brake suit the motor for dry-room, horizontally mounted service where external load-side braking can be managed by the drive.
