Product Description:

The 8LSE66.EB030D114-3 is a three-phase synchronous servo motor produced by B & R Automation for the 8LS Synchronous Motors series. Within automated machinery, it converts electrical power into precise rotational motion for positioning tasks, and its 8LSE designation identifies it as a liquid-cooled model in the platform. The unit attaches through a mounting flange and is delivered without a holding brake, so any axis that must stay fixed when power is removed must rely on external clamping. A keyed shaft end transmits torque directly to couplings or gearboxes, and product revision 3 indicates the mechanical build of this configuration.

The stator is cooled through a liquid-cooled A-side flange that extracts heat without airflow, allowing continuous operation at the rated speed of 3000 rpm. A flange dimension of 190 mm provides the interface pattern for frame mounting, while power and feedback cables exit through an angled swivel connector that eases routing in confined installation spaces. Internally, the motor uses a three-phase synchronous winding that produces constant torque across its operating speed range. No oil seal is fitted on the shaft, so the installation environment must be protected from fluid splashes that could reach the shaft opening. Connection hardware consists of a single plug-in connector block, which provides a centralized point for the required electrical connections. The housing is prepared for installation with a standard mounting flange and does not require additional mounting adapters.

Rotor position is measured by an encoder that uses inductive EnDat signaling, and data transmission follows version 2.1 for bidirectional communication with the drive. The position data stream provides 19/12 bits of single-turn and multi-turn resolution, allowing the control system to track both the angular position within one turn and the accumulated position across multiple turns. The counting system remembers up to 4096 revolutions, supporting absolute position feedback after a loss of power. Length code 6 provides an extended motor housing that accommodates the active components while maintaining the proportions required for this frame. The lack of an internal brake reduces rotating mass, which supports responsive acceleration when external holding equipment is available for stationary loads.
