Product Description:
The 8LSA66.EA022D000-3 synchronous motor is produced by B & R Automation as part of the 8LS Synchronous Motors series. Classified as a three-phase synchronous machine, it is intended for driving axes in automated production lines where constant torque and repeatable positioning are required. The model carries the internal designation 8LSA and uses the standard build without reinforced bearings, making it suitable for general-purpose rotary applications. Its permanent-magnet design supports responsive acceleration and precise speed regulation when paired with a compatible servo drive.
During continuous operation, the rotor reaches a rated speed of 2200 rpm, balancing torque production with the motor’s thermal limits. Heat is removed by a self-cooling design that relies on free air circulation, so no external blower is necessary. A 190 mm square flange provides an accurate reference surface for alignment with gearboxes or machine frames. Position feedback is generated by an inductive EnDat sensor that communicates through EnDat 2.1, providing digital position data to the drive. Power and signal lines exit through an angled swivel connection, allowing the cable orientation to be adjusted to suit the machine layout. A keyed connector prevents incorrect mating and helps maintain suitable cable bend radii in energy-chain installations. Length code 6 indicates the active stack depth used for this motor configuration.
The motor uses a smooth shaft, eliminating keyways and reducing stress concentrations when clamp-style couplings are installed. Because the motor has no holding brake, an external clamping device is required if the shaft must remain mechanically locked after power is removed. The housing is produced as revision 3, incorporating updates that remain compatible with the applicable drive parameters. An oil seal is not installed, so an external seal should be added when the motor is mounted next to a lubricated gear stage. The encoder provides a 19-bit single-turn resolution, corresponding to 524,288 discrete positions per revolution. Its single-turn configuration does not track complete revolutions after power is removed, so the controlled axis may need to perform a homing sequence when the system starts.
