8LSC86.E1020D000-3 by B & R Automation

The 8LSC86.E1020D000-3 motor is produced by B&R Automation within the 8LS Synchronous Motors series. It is a three-phase synchronous unit intended to deliver precise rotary positioning and continuous torque to conveyors, pick-and-place axes, and other motion stages in automated production cells. Its synchronous design supports accurate speed regulation and repeatable motion when the axis must stay coordinated with tooling or adjacent drives.

Mechanical integration is based on a mounting flange with a 240 mm interface, and the large diameter supports rigid attachment to heavy machine frames. The housing follows the 8LSC designation, indicating a standard build without a reinforced bearing, and the stack length uses length code 6. A smooth shaft simplifies coupling to keyed or clamped hubs, while the absence of an oil seal limits use to dry or purged environments. Cooling is handled by a built-in fan assembly, allowing the stator to maintain its thermal profile during continuous operation at 2000 rpm. Power and feedback leads exit through an angled swivel outlet and terminate in a single connector, which helps reduce cable strain during axis rotation. No holding brake is fitted, so external clamping devices must secure vertical loads. Internal updates are reflected in product revision 3.

Position feedback is managed by an Optical EnDat system that streams absolute position data to the drive with an effective resolution of 13/12 bits for single-turn and multi-turn layers. The encoder supports EnDat 2.1, enabling automatic backup of calibration data and fast diagnostic access through the control system. Multi-turn capability of up to 4096 revs eliminates homing cycles after power loss and helps the axis return to operation more quickly. This feedback arrangement lets the controller monitor rotor angle continuously, which supports stable commutation and repeatable positioning during short indexing moves or longer travel sequences. Encoder mounting tolerances remain stable when external radial forces stay within the limits of the standard bearing arrangement, so shaft alignment must be maintained during installation.
