Product Description:
The 8LSA43.ee045ffgg-3 is a synchronous servo motor manufactured by B&R Automation for the 8LS Synchronous Motors series. As a rotary actuator, it converts controlled electrical energy into rotational motion so that packaging stations, pick-and-place axes, or indexing tables can maintain precise position and velocity profiles within an automated cell. Its three-phase stator winding works with a compatible drive controller to produce electronically commutated torque over a wide speed range, providing a compact source of motion that can be mounted directly to mechanical loads without intermediate gear trains.
The stator terminals use a connector, providing a detachable electrical connection and eliminating hard-wired joints in the cabinet. Thermal management relies on self-cooling with free air circulation; heat generated in the windings dissipates through the housing surface, so no external fan or liquid cooling circuit is required. A square mounting interface measuring 100 mm across establishes the flange size and aligns the motor with precision-machined faces on gearboxes or machine frames. Under continuous excitation, the rotor can reach 4500 rpm, supporting rapid indexing or high linear throughput when coupled to belts or lead screws. The motor uses a three-phase synchronous design, so shaft movement follows the drive controller’s commanded output and supports repeatable motion under changing mechanical loads.
The ordering key uses the family designation 8LSA, placing the motor within the corresponding 8LS product group. Its primary fastening surface is a mounting flange, allowing the unit to be secured directly to a suitable machine plate while maintaining alignment with the connected load. The motor has a length code of 3, indicating the magnetic stack length selected for this torque class and housing configuration. It is built to product revision 3, which indicates the release level of the unit’s documented design. These attributes support integration with compatible servo drives, feedback wiring, couplings, and machine mounting surfaces while preserving the controlled acceleration and positioning behavior expected from a synchronous motor.
