8LSA43.E1030C600-3 by B & R Automation

The 8LSA43.E1030C600-3 is a three-phase synchronous motor built by B&R Automation and belongs to the 8LS Synchronous Motors series. Designed as an active axis element, it converts electrical power into regulated torque and speed for positioning and velocity loops in automated machinery. The motor fits standard industrial mounting flanges, letting machine builders integrate rotary motion without external gearboxes. Its configuration code 8LSA indicates a standard build without reinforced bearings, making it suitable for moderate radial loads common in packaging lines, handling modules, and small conveyor drives.

The motor reaches a rated speed of 3000 rpm, which is its nominal operating speed when driven by the corresponding inverter. The flange dimension of 100 mm establishes the interface pattern and centers the stator on the machine frame. The self-cooling free-circulation design removes heat through the housing surface, eliminating the need for external fans. Power and feedback cables terminate through a straight top connector, simplifying routing in compact cabinets. Position data come from an Optical EnDat sensor that provides 13/12 bits of single-turn and multi-turn resolution for fine interpolated control.

The encoder's multi-turn register stores up to 4096 revolutions, so machines retain absolute position after power cycles. A smooth shaft delivers torque to couplings while reducing keyway-related stress, and an oil seal helps block dust or coolant from reaching the bearings. The housing includes a mounting flange that matches length code 3, giving a compact axial size for cells where depth is limited. Because a holding brake is not present, the motion controller must supply dynamic braking or mechanical locks for vertical loads. Product revision 3 maintains protocol compatibility with EnDat 2.1 drive interfaces.
