Product Description:
The 8LSA55.D0030D000-1 is an AC servo motor manufactured by B&R Automation and assigned to the 8LS Synchronous Motors series. As a three-phase synchronous unit, it converts electrical energy into controlled mechanical rotation for motion axes in industrial automation equipment. The 8LSA designation indicates the standard build without reinforced bearings, making the motor a compact drive element for packaging, assembly, and material-handling machinery that requires precise speed and position control.
The motor has a rated speed of 3000 rpm, allowing compatible inverters to execute rapid positioning cycles without overspeeding mechanical components. Its three-phase synchronous design minimizes torque ripple because the electromagnetic field remains synchronized with the stator excitation. Position feedback comes from an optical EnDat encoder that transmits absolute position data through protocol revision 2.2, enabling high-resolution commutation with minimal cabling. The motor attaches to gearboxes or machine frames through a square flange measuring 142 mm across, providing a stable mounting surface for accurate shaft alignment.
Thermal management relies on self-cooling with free air circulation, so no external blower or liquid-cooling loop is required when the motor operates within its permitted load range. Power and feedback conductors exit through an angled swivel connector, which reduces cable bending requirements inside crowded enclosures and allows the connection angle to suit the installation. The rotor transmits torque through a smooth shaft, so the coupling must clamp directly onto the journal because no keyway is present. Feedback resolution is 25/0 single-turn and multi-turn bits, and the encoder provides single-turn position capability for axes that perform a homing routine after power-up. The motor uses length code 5 for the active stack and has a standard bearing arrangement. It is supplied without a holding brake or oil seal.
