Product Description:

The 8LWA13.B9045S200-0 is a high-torque servo motor produced by B&R Automation within the 8LWA High Torque Servo Motors series. It serves as the rotary actuator in automated machinery, supplying controlled torque and speed so that positioning systems, feeders, and gantries can follow programmed motion profiles with repeatable accuracy. Its design is suited to compact motion axes that require stable response during frequent starts, stops, and direction changes.

This motor employs single-cable technology, so power and feedback share one hybrid line that exits the housing on an angled swivel to reduce external wiring. At a nominal speed of 4500 rpm, the smooth shaft delivers mechanical output without keyway-related imbalance. The integrated holding brake supplies 0.35 Nm of static torque to maintain axis position when power is removed. Its enclosure is rated IP64, guarding against dust ingress and water spray during normal operation. Mechanical resilience includes tolerance of shocks up to 2000 m/s², allowing installation on fast-indexing pick-and-place heads. The motor has size code 1, length code 3, and no oil seal, so the installation environment should be kept consistent with that shaft arrangement.

Position feedback is generated by an EnDat 2.2 optical encoder with a precision window of +120 arcminutes. It supports single-turn and multi-turn evaluation through a resolution of 19/12 bits, its internal counter tracks up to 4096 revolutions for absolute position recovery after power cycles, and it connects to the drive through the same hybrid lead that carries phase current. Thermal management relies on self-cooling, so airflow around the housing must remain unobstructed to dissipate losses. This arrangement supports accurate feedback handling during repeated indexing and synchronized servo motion.
