Product Description:

The 8LSA45.EA045D200-0 is a three-phase synchronous motor manufactured by B & R Automation as part of the 8LS Synchronous Motors series. It operates as a servo actuator in production lines and packaging equipment where accurate speed and position control are essential. When paired with a compatible drive, it converts controlled current into precise rotary motion for indexing, transfer, and synchronized machine movements. The 8LSA designation indicates a standard mechanical build without reinforced bearings, and the compact stator with a lightweight rotor fits tight installation spaces while still delivering the torque density needed for continuous-duty machine cycles.

The motor relies on a self-cooling airflow path, so no external fan or liquid circuit is required to remove heat during continuous operation. A rated speed of 4500 rpm allows the axis to follow high-throughput motion profiles before field weakening is needed. The IEC-compliant flange face measures 100 mm, providing a consistent mounting interface for gearboxes or direct-coupled loads. Power and feedback leads exit through an angled swivel connection that eases cable routing in compact cabinets while maintaining strain relief. Position information is generated by an Inductive EnDat encoder with digital temperature monitoring, and its 19/0-bit single-turn resolution supplies fine feedback data to the drive. The connection hardware uses a keyed circular connector sealed by the mating plug, and length code 5 identifies the active stack height.

EnDat protocol revision 2.1 supports bidirectional parameter exchange and electronic nameplate reading. During power-off events, a standard holding brake secures the load without external actuators, while a smooth shaft transfers torque to the driven element. The integrated mounting flange supports rigid axial alignment, and the lack of an oil seal makes the motor suitable for dry environments.
