8LSA45.ee030ffgg-3 by B & R Automation

The 8LSA45.ee030ffgg-3 is an AC servo motor built by B&R Automation and supplied within the 8LS Synchronous Motors series. This unit serves as a torque-generating element in industrial automation, pairing with a matched drive to convert electrical input into controlled rotary motion for indexing tables, pick-and-place axes, and similar mechanisms. By working within digital position loops, the motor provides repeatable shaft speed and angle control for synchronized multi-axis production lines.

Electrical and mechanical interfaces are routed through a single connector that carries power and feedback in one plug, which reduces cable complexity around the motor. Thermal dissipation relies on self-cooling through free air circulation, so the housing releases heat directly to the surrounding air without external fans or liquid jackets. The front face follows the DIN 42948 pattern and uses a 100 mm square flange, which suits machine interfaces built around that mounting size. Under nominal excitation, the rotor reaches 3000 rpm, a speed suitable for general positioning tasks without requiring gearbox multiplication. Axial fastening is provided by a mounting flange, allowing secure attachment to machine plates while keeping the stator aligned with the driven load.

The electromagnetic core uses a three-phase synchronous design, so torque is produced in step with the sinusoidal current sequence supplied by the inverter. Within the product code, the family identifier 8LSA distinguishes this motor from higher-inertia members of the range, while the length index 5 indicates the active stack height selected for applications that need greater continuous power without increasing frame width. Manufacturing changes are tracked by revision 3 in the product code. This revision marks the recorded motor build used for identification within the series.
