8LSE66.EB030D114-3 by B & R Automation

B & R Automation's 8LSE66.EB030D114-3 belongs to the 8LS Synchronous Motors series and is categorized as a three-phase synchronous unit for servo-class motion tasks in industrial automation. The motor's factory designation is 8LSE, and the product carries revision level 3. When coupled with a matched inverter, it delivers closed-loop torque and speed control for packaging lines, material-handling axes, and other applications that demand repeatable positioning and rapid cycle times.

The motor has a rated speed of 3000 rpm, giving the drive ample headroom for acceleration profiles used in indexing systems. Heat is extracted through a liquid-cooled A-side flange; routing coolant through this interface stabilizes winding temperature and allows higher continuous torque than air-cooled designs. A 190 mm flange aligns the stator precisely to machine frames, while length code 6 indicates the active stack height within the 8LS mechanical grid. Position feedback is supplied by an Inductive EnDat encoder, providing non-contact scanning for resistance to vibration and magnetic fields. Its signal granularity equals a 19/12-bit resolution for single-turn and multi-turn operation, enabling fine speed regulation at low velocities. The motor is delivered without a holding brake, so external measures must secure vertical loads.

Power and feedback leads exit through an angled swivel connector, simplifying cable routing in tight cabinets and matching the specified connector hardware. The feedback channel supports EnDat 2.1 command sets, so absolute position and diagnostic data travel over a single pair without separate Hall sensors. Multi-turn capability extends to multi-turn 4096 revs, letting a controller maintain absolute shaft position after power loss. The motor uses a keyed shaft end to transmit torque to pulley or coupling hubs, and the absence of an oil seal minimizes drag where external contamination is not a concern.
