Product Description:

The 8LSA36.R2045D300-3 is a three-phase synchronous motor produced by B & R Automation within the 8LS Synchronous Motors series. Designed as a drive element for industrial automation, it converts electrical energy into controlled mechanical motion for positioning tasks on packaging lines, assembly stations, and similar machinery. Its compact flange dimension and integrated feedback support direct attachment to machine frames, providing reliable torque and speed control when paired with compatible B & R servo amplifiers. By combining power, feedback, and brake functions in a sealed housing, it simplifies wiring in distributed servo architectures.

The active section follows length code 6 and reaches a rated speed of 4500 rpm, enabling fast cycle times while staying within the thermal limits of its self-cooling housing. A resolver on the rotor supplies position data for closed-loop feedback without optical encoders. The integrated standard holding brake secures the axis during power-off conditions. Installation uses a 91.3 mm square flange, so alignment with gearboxes or direct-drive loads is straightforward. The motor designation 8LSA indicates the standard bearing set and three-phase winding construction used across the series.

The electrical and mechanical interfaces are arranged to reduce cable stress. Power and feedback exit through an angled connection that can swivel, which helps route cables in tight machine spaces. Shaft torque passes through a keyed shaft, and a positioning accuracy of 6 arcmin at the flange face supports precise alignment. Because there is no oil seal, the housing has lower drag and suits dry environments where lubricant exclusion is acceptable. The motor carries product revision 3, and its mounting flange pattern fits common B & R Automation layouts.
