Product Description:

The 8LSA44.R0045D000-0 is a three-phase synchronous servo motor produced by B&R Automation for the 8LS Synchronous Motors series. Its 8LSA designation indicates the standard configuration without reinforced bearings, while length code 4 identifies the active stack depth. The motor supplies regulated torque and speed for packaging lines, machine tools, and material-handling cells. It forms the electromechanical interface between a compatible drive amplifier and the moving load, converting controlled electrical power into rotary motion.

At a rated speed of 4500 rpm, the rotor reaches its continuous operating point, allowing gear ratios or direct-drive arrangements to be matched to application throughput. A 100 mm square flange provides a consistent reference face for attachment to gearboxes or machine frames while maintaining a uniform shaft height. Position data comes from an integrated resolver, which delivers sine-cosine signals to the controller for closed-loop motion control. The feedback system has a mechanical accuracy of 10 arcmin, supporting precise position and speed regulation under changing loads. Heat leaves the stator through self-cooling with free air circulation, so ambient air passing along the housing fins helps keep the winding temperature within its allowable range.

Cables exit through an angled swivel connector that can rotate by up to 300 degrees, allowing the cable direction to suit the installation while reducing strain on the connection. The motor has a smooth shaft that supports backlash-free clamp or collet couplings. Its machined front face accepts ISO mounting bolts for accurate concentric alignment with the connected equipment. The motor has no holding brake, so a vertical axis requires an external clamp or another suitable retaining device if power is lost. An oil seal is omitted to reduce friction during high-speed operation, making the motor most appropriate for installations where the shaft area is not exposed to lubricants or other contaminants.
