Product Description:
The 8LSA46.E3045D000-0 is a servo motor manufactured by B & R Automation as part of the 8LS Synchronous Motors series. It converts regulated three-phase drive current into controlled mechanical rotation for positioning tables, pick-and-place heads, and packaging axes in automated equipment. The motor’s housing, flange, and feedback geometry follow the series format, supporting integration with established bracket layouts and cable assemblies. Its synchronous operation enables the connected servo drive to regulate torque, speed, and position throughout repetitive machine cycles.
The stator-rotor system uses a three-phase synchronous design, which delivers stable torque and precise phase alignment for modern servo control loops. The motor has a rated speed of 4500 rpm, supporting high cycle rates when combined with suitable gearing. A 100 mm flange diameter provides the mounting interface and centering pilot for compatible gearboxes. The motor has a length index of 6, indicating the active magnetic stack selected for this frame size. Output torque is transmitted through a smooth shaft end, permitting the use of shrink discs or clamping couplings where minimal backlash is required. The fixed mounting flange centers the motor axially, allowing direct attachment to reducers or belt-drive assemblies without spacer plates.
Heat is removed by self-cooling through free air circulation, which relies on ambient airflow and eliminates the need for external blowers or liquid lines. Cables exit from the rear with an angled, swiveling orientation, allowing them to be directed toward nearby cable trays without tight bends. This rotatable cable arrangement uses a sealed connector interface that helps maintain strain relief and protects the electrical connections from surrounding contaminants. The unit is supplied without a holding brake, reducing motor mass and making it suitable for horizontal axes that do not require static load retention. The lack of an oil seal reduces shaft drag, while the rigid mounting arrangement maintains alignment with the connected mechanical assembly.
