Product Description:
The 8LSA66.EB030D000-1 is a servo-grade drive motor produced by B&R Automation within the 8LS Synchronous Motors series. It serves as the mechanical element in industrial automation axes, converting controlled electrical energy into repeatable rotary motion for gantry heads, wrapping stations, and indexing tables. A flange interface allows direct installation on machine frames, and the built-in encoder channel communicates rotor position to the drive controller for closed-loop speed and torque regulation. This arrangement enables the controller to adjust motor current in response to position commands and changing loads during automated operation.
Within the 8LSA designation, the letter sequence indicates a standard build without a reinforced bearing, while length code 6 indicates a medium magnetic stack. The stator uses a three-phase synchronous winding, delivering balanced phase currents while minimizing cogging. Under rated excitation, the rotor reaches 3000 rpm, a speed that aligns with common four-pole inverter outputs. Cooling relies on a self-cooling housing with free air circulation that guides ambient air over the external ribs, eliminating the need for auxiliary blowers. Rotor angle is measured by a noncontact inductive EnDat encoder whose signals support real-time commutation. A flange with an outside diameter of 190 mm supplies the stiffness needed for gearhead or belt-pulley attachments without distorting the frame.
Power and feedback cables leave the housing through an angled swivel termination fitted with a keyed connector, simplifying cable routing in restricted cabinets. The feedback channel operates with EnDat version 2.1, providing an absolute resolution of 19 single-turn bits and 12 multi-turn bits. It retains position information for up to 4096 revolutions, allowing the drive to determine the stored shaft position across multiple turns. The motor has a smooth shaft without a holding brake or oil seal, so external load-retention or sealing components may be required for vertical loads or contaminated environments. A mounting flange pattern based on IEC metric dimensions supports installation across a range of compatible machine platforms.
