Product Description:
The 8LSA75.EA030D600-3 is a three-phase synchronous motor manufactured by B&R Automation for the 8LS Synchronous Motors series. It functions as a rotary actuator in automated machinery by converting inverter output into controlled torque for positioning tooling, conveyors, and machine axes. Its synchronous design supports precise speed regulation and repeatable motion when paired with a compatible servo drive. The 8LSA designation indicates a standard configuration without a reinforced bearing, while the integrated mounting flange allows direct attachment to a gearbox or machine frame.
Power and feedback leads exit through an angled swivel connector that can be rotated to reduce cable strain and accommodate the available routing space. The mating interface uses a keyed connector that helps prevent incorrect alignment during installation. A square flange measuring 190 mm provides the mounting pattern needed for rigid attachment to the driven equipment. Under continuous operation, the motor reaches a rated speed of 3000 rpm, allowing the selected gear ratio to provide the required output speed and torque. Stator heat is dissipated through self-cooling with free air circulation, eliminating the need for an external fan or liquid-cooling circuit. This passive cooling method requires enough open space around the housing for air to circulate and carry heat away from the motor surfaces.
Position feedback is generated by an inductive EnDat encoder that communicates with the drive through protocol version 2.1. The single-turn sensor provides a 19/0-bit resolution, allowing absolute shaft position to be available after a power cycle without a separate homing movement. Mechanical output is transmitted through a smooth shaft with an oil seal, which accepts clamp or shrink-disk couplings while helping prevent lubricant from reaching the motor bearings. The motor is supplied without a holding brake, so a drive-generated holding torque or an external brake must secure static loads after power is removed. Its length code is 5, which identifies the axial housing arrangement used for this model. Product revision 3 indicates the applicable design generation for component selection and system documentation.
