8LSA43.E3045D000-0 by B & R Automation

The 8LSA43.E3045D000-0 is a three-phase synchronous motor produced by B&R Automation for the 8LS Synchronous Motors series. In a multi-axis automation cell, it serves as the electromechanical link between the servo drive and the load, supplying repeatable torque and speed for pick-and-place heads, feeders, and compact spindle stations. The 8LSA configuration places it in a standard mechanical version of the platform, which helps keep inertia low for fast motion profiles in compact machinery. This makes the motor suitable for axes that need quick acceleration, stable speed control, and repeatable positioning during frequent start-stop cycles.

The wiring exits the housing through an angled swivel conduit, so cables can be routed in tight enclosures without sharp bends at the motor outlet. Power and feedback lines terminate on a single industrial connector, which keeps the interface compact and provides a keyed connection for secure mating. Heat is removed by self-cooling through free air circulation, eliminating the need for external fans or liquid cooling plates. A square flange measuring 100 mm on each side provides an accurate mounting reference, and a nominal operating speed of 4500 rpm supports direct coupling to high-speed machinery without secondary gearing.

The motor uses standard construction without reinforced bearings, making it suitable for moderate radial loads in belt-driven or directly coupled systems. A face-mounted flange allows quick attachment to machine plates or gearbox inputs, and the rotor has a smooth shaft that works well with press-fit hubs or shrink discs. Because the shaft is plain rather than keyed, torque transmission depends on the selected hub or clamping element at the machine side. Length code 3 indicates a medium active stack that balances torque density with installation depth. The motor is supplied without a holding brake or oil seal, so any external clamping device or contamination barrier can be added only where the application requires it.
