8LSA86.E0020D100-0 by B & R Automation

B&R Automation manufactures the 8LSA86.E0020D100-0 for the 8LS Synchronous Motors series. The model serves as a compact drive element that delivers precise rotary motion for indexing tables, pick-and-place axes, and coordinated conveyor zones in automated cells. The 8LSA designation indicates a standard build without reinforced bearings, while still supporting the feedback functions needed for closed-loop servo control. This makes the motor suitable for machinery that depends on accurate speed regulation and repeatable positioning during frequent duty cycles.

The housing follows the standard 8LSA configuration and uses length code 6 for its active stack. A mounting flange of 240 mm mates directly to machine plates, and the shaft end includes a key for positive torque transfer. Power and feedback leads exit through a connector with an angled swivel direction, which helps route cables around nearby machine structures. Thermal management relies on self-cooling with free air circulation, so ambient air removes heat without auxiliary fans or liquid circuits. The motor has no oil seal, which suits installations where the surrounding area remains clean and radial loads stay within the standard bearing arrangement. Under nominal conditions, the rotor reaches 2000 rpm, giving a practical balance between speed and torque for packaging, assembly, and transfer modules.

Position feedback is provided by an optical EnDat encoder that uses version 2.1. Its single-turn architecture resolves rotor position with 13/0 bits, making it suitable for applications that reference a known position within one revolution. Because the motor has no holding brake, stationary loads must be secured by the machine or by electrical holding torque from the drive. The unit operates as a three-phase synchronous motor, allowing sinusoidal current control to align the stator field with rotor position and maintain smooth torque across the commanded speed range. This arrangement supports controlled motion in automated systems that require stable response during indexing and coordinated axis movement.
