8LSA86.E1020D000-0 by B & R Automation

The 8LSA86.E1020D000-0 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. As a standard 8LSA configuration, it is intended for fixed-speed and servo-controlled axes in industrial automation lines where compact flange mounting and integrated feedback simplify installation. It operates in closed-loop servo systems where precise speed and position are required on packaging, material-handling, and processing equipment.

At a rated speed of 2000 rpm, the rotor supplies continuous motion while remaining within the thermal margin enabled by its self-cooling airflow, which relies on free circulation rather than an external blower. The mechanical interface uses a 240 mm flange, allowing direct attachment to gearboxes or frames without adapter plates. Position feedback is delivered through an optical EnDat 2.1 encoder that communicates absolute data to the drive; its single-turn and multi-turn counters combine to give a resolution of 13/12-bit, supporting tight velocity loops and accurate repositioning during start-stop cycles.

For wiring, the power and signal conductors exit through an angled swivel connector, letting the plug be oriented to minimize strain in tight cabinets. The stator stack uses length code 6, which offers a balance between torque output and motor mass for medium-duty axes. Mechanical holding force during power-off must be provided by the machine because the motor is delivered without a holding brake. Its absolute encoder tracks position over up to 4096 revolutions in multi-turn operation, eliminating homing routines after shutdown and retaining position data even if motion occurs while the motor is de-energized. The smooth shaft, flange mounting holes, and absence of an oil seal suit clean production zones where leakage protection is handled elsewhere.
