Product Description:
The 8LSA44.EB030D000-0 is a three-phase servo motor produced by B & R Automation within the 8LS Synchronous Motors series. This unit converts inverter-generated stator currents into controlled shaft rotation, supplying precise torque and velocity for packaging lines, assembly robots, and other computer-controlled machinery where repeatable motion profiles are critical. Its standard 8LSA configuration uses standard rather than reinforced bearings, reducing rotating inertia and overall weight for faster cycle times. The paired servo drive uses feedback to correct position and speed errors as loads change, helping the axis follow programmed acceleration, travel, and deceleration commands.
As a three-phase synchronous motor, the rotor locks magnetically to the rotating field, permitting direct speed regulation up to 3000 rpm. A 100 mm flange provides the mounting datum, so the housing bolts directly to standardized mechanical interfaces. Heat is removed through self-cooling, and free air circulation around the frame is sufficient for the intended load profile. Position feedback is handled by an inductive EnDat 2.1 encoder that communicates absolute position to the drive with interference-tolerant digital signals. The encoder data allows the control system to coordinate shaft movement with pneumatic, hydraulic, or belt-driven machine modules.
The motor is supplied without a holding brake, so load retention during power loss must be managed externally. Because the motor has no oil seal, its smooth shaft is intended for clean environments or installations with separate contamination barriers. Power and feedback lines exit through an angled swivel connection that eases cable routing in confined spaces while reducing sharp bends and strain near the motor housing. The feedback circuit offers 19/12-bit resolution and tracks up to 4,096 mechanical revolutions, allowing fine interpolation during multi-turn positioning with the inductive encoder. Absolute multi-turn feedback preserves the known shaft position through routine power cycles, reducing the need to perform repeated axis homing. The stator uses length code 4 for this motor configuration.
