8LSE84.E1015D000-0 by B & R Automation

The 8LSE84.E1015D000-0 belongs to the 8LS Synchronous Motors series manufactured by B&R Automation. Within this range, it is supplied as a rotary servo motor for closed-loop motion axes in automated machines and robotic cells. The unit converts drive inverter output into precisely regulated torque and speed so that positioning, contouring, and coordinated line control can be carried out with minimal following error.

This model combines mechanical size and feedback accuracy for medium-torque applications. It has a rated speed of 1500 rpm and a 240 mm square flange that aligns with standardized machine frames. The liquid-cooled A-side flange removes heat directly through the mounting interface to keep the windings within their thermal limits. Position data are delivered by an optical EnDat sensor that uses protocol version 2.1, which supports digital transmission with high noise immunity. Inside the encoder, a resolution of 13/12 bits for single-turn and multi-turn feedback provides precise position processing, and the multi-turn counter tracks up to 4096 revolutions without battery support. These feedback features allow the drive to perform commutation, velocity regulation, and absolute position detection immediately after power-up, eliminating reference routines and shortening cycle times.

Cabling is simplified because power and feedback emerge from an angled swivel outlet that accepts a keyed connector, so cable routing can be adapted to different cabinet orientations. A smooth shaft mates to backlash-free couplings, and the mounting flange provides rigid face installation without separate feet or torque arms. The motor follows a standard 8LSE configuration with length code 4, indicating the active stack height selected for its torque class. It is a three-phase synchronous design without a built-in holding brake, and it has no oil seal, so external sealing may be required where fluids are present.
