8LSA44.EB060D800-3
The 8LSA44.EB060D800-3 is a three-phase synchronous motor manufactured by B&R Automation as part of the 8LS Synchronous Motors series. The unit converts electrical energy into precise rotary motion for positioning or velocity-controlled axes in packaging machines, assembly cells, and material-handling stations. Its integrated absolute encoder feeds back exact rotor position so that the drive system can execute coordinated multi-axis moves and maintain accuracy during rapid start-stop cycles. The motor can be coupled to gears, pulleys, or timing belts for direct transmission into the driven mechanism.
At a rated speed of 6000 rpm, the motor supports high throughput before field weakening is necessary. The mounting interface is a 100 mm square flange, allowing direct fit to IEC drillings without adapter plates. A smooth shaft end simplifies alignment and reduces fretting on couplings. Feedback comes from an inductive EnDat encoder that exchanges data through the EnDat 2.1 protocol. Its 19/12 bits of single-turn and multi-turn resolution provide fine command granularity, and the internal register stores up to 4096 revolutions so the axis can retain position information after power loss. The three-phase winding allows the unit to operate with standard vector inverters.
Heat is removed through self-cooling and free air circulation, eliminating the need for external blowers. Power and encoder leads exit through an angled swivel connector that keeps cable loops compact and protects contacts from torsion. A standard holding brake secures the load when power is off, and a front oil seal helps block lubricants or coolant from entering the stator cavity. Length code 4 indicates the housing depth for this variant, product revision 3 identifies the current electrical build, and the 8LSA designation indicates the standard configuration without a reinforced bearing.
