Product Description:
The 8LSA55.EB045D200-1 is a motor manufactured by B&R Automation within the 8LS Synchronous Motors series. The internal 8LSA designation indicates the standard configuration without a reinforced bearing, while length code 5 identifies the active stack height for medium-torque applications. Intended for industrial automation, the unit supplies precise axis movement for packaging, printing, and material-handling equipment. Its three-phase synchronous design operates with compatible servo inverters, while a mounting flange enables direct installation on machine frames. A smooth shaft facilitates connection to gearboxes or belt pulleys, and the absence of an oil seal makes the motor best suited to dry environments.
The power and feedback conductors exit through an angled swivel connector, simplifying cable routing in compact installations. Thermal management uses self-cooling with free air circulation, so no external fan is required. The rotor reaches a rated speed of 4500 rpm, allowing rapid indexing within the mechanical limits of its standard bearings. A square face with a 142 mm flange dimension supports alignment with compatible machine mounting surfaces. Position data is generated by an inductive EnDat encoder that transmits absolute values over a digital connection. Its inductive operating principle also provides greater resistance to contamination than an optical sensing system.
The feedback system provides a 19/12-bit resolution, combining precise single-turn position measurement with multi-turn counting for position recovery after shutdown. The multi-turn counter records up to 4096 revolutions, allowing the controller to retain the axis position without requiring a homing movement after power is restored. A standard holding brake secures vertical or suspended loads whenever drive power is removed. The brake can prevent unintended shaft movement while the axis is stationary, but operational stopping remains the responsibility of the servo control system. Because no oil seal is installed, the shaft area must remain protected from pressurized fluids and other conditions that could allow liquid to enter the motor. Feedback communication uses EnDat version 2.1, enabling digital transfer of position information to a compatible servo drive.
