8LSA66.EB030D000-1 by B & R Automation

The 8LSA66.EB030D000-1 is a three-phase synchronous motor produced by B & R Automation as part of the 8LS Synchronous Motors series. Intended for servo axes in packaging equipment, handling gantries, and CNC stations, the unit delivers coordinated torque when driven by a compatible inverter. Its compact housing, standard bearing set, and integrated feedback support repeatable motion in modular machine frames where accurate timing and consistent positioning are required through frequent start-stop cycles.

At a rated speed of 3000 rpm, the motor supports continuous servo operation in high-cycle automation equipment. It uses self-cooling with free circulation, so air must move freely around the housing rather than through an external blower path. The mounting flange has a diameter of 190 mm, which helps align the motor with matching machine interfaces and couplings on its smooth shaft. Position feedback is supplied by an Inductive EnDat sensor that communicates through version 2.1, giving the drive digital position data for closed-loop control. A single sealed connector carries power and feedback, while the motor uses standard bearings and omits an oil seal to reduce friction at high speed.

The feedback system provides 19/12 bits of single-turn and multi-turn resolution, and absolute tracking is maintained across up to 4096 revolutions. The electrical interface uses an angled swivel connector, which allows the cable outlet to be rotated for cleaner routing in compact installations. The motor has no holding brake, so any required static holding torque must come from the drive or an external mechanical device. Length code 6 sets the housing stack height, and the absence of reinforced bearings keeps the rotor assembly suited to applications that need low inertia together with absolute position feedback.
