Product Description:
The 8LSA45.ea045d000-0 synchronous motor is produced by B&R Automation for the 8LS Synchronous Motors series and serves as a rotary actuator in industrial automation. It transforms controlled current from a servo inverter into repeatable angular motion for pick-and-place stations, small conveyors, or indexing tables. The motor pairs a permanent-magnet rotor with a stator optimized for high dynamic response, making it suitable for coordinated multi-axis systems that rely on precise velocity control and tight position tolerances. The series mounting pattern and compact housing allow straightforward installation in machine frames where space is limited.
The unit is a three-phase synchronous machine, so its rotor flux remains synchronized with the sinusoidal stator field generated by the drive. A self-cooling system with free air circulation removes winding heat through natural convection along the frame fins, eliminating the need for an external blower. Power, signal, and protective ground conductors are routed through a single connector, reducing wiring clutter and simplifying installation. Mechanical attachment is provided by a 100 mm square flange that conforms to IEC motor sizing, permitting direct coupling to gearboxes or mounting plates. Under continuous duty, the shaft can maintain 4500 rpm, providing high linear speeds when connected to belt transmissions or screw drives.
The model is classified as 8LSA within the motor platform, and its configuration uses a standard bearing arrangement without reinforcement. Conventional deep-groove bearings support moderate radial and axial loads, while output torque is transferred through the shaft to the connected load. The magnetic stack uses length code 5, providing a balance between continuous torque capacity and overall motor depth for medium-inertia applications with limited installation space.
