Product Description:
The 8LSA44.DA022S700-3 is an electric servo motor developed by B & R Automation for the 8LS Synchronous Motors series. Designed for integration into packaging machinery, pick-and-place axes, and other coordinated motion applications, the unit converts drive controller output into precise rotary movement for industrial automation processes. It uses a three-phase synchronous topology and internal position feedback, allowing the controller to perform rapid closed-loop positioning under variable load conditions. This arrangement supports accurate speed and position regulation during repetitive machine cycles.
The motor has a rated speed of 2200 rpm, enabling it to deliver moderate shaft velocities without overspeeding standard mechanical components. Power and feedback lines exit through a single-cable hybrid solution, which simplifies installation by combining the three-phase power conductors and EnDat signal lines in one jacket. Position sensing is handled by an inductive EnDat encoder that provides the controller with rotor position data. The motor uses self-cooling through free air circulation to transfer heat to the surrounding air without auxiliary fans. Its mounting interface has a 100 mm square flange that aligns with common IEC sizing conventions. The attached connector hardware mates directly with compatible B & R drive cables. EnDat version 2.2 supports high-resolution, bidirectional communication between the motor and drive controller.
The motor uses standard bearings without reinforcement, making it suitable for horizontal axes with moderate mechanical loads. A mounting flange supports accurate alignment with the driven machine assembly. The motor has a shaft with a key for positive torque transfer to a coupling, pulley, or gearbox. Feedback resolution is 19/0 bits, and the encoder provides single-turn position information within one mechanical revolution. Because the motor does not include a holding brake, an external brake must be used when the application requires the shaft to remain stationary without drive torque. An oil seal helps prevent lubricant leakage at the shaft interface. Length code 4 indicates the magnetic stack height, while product revision 3 identifies the current update level within the 8LSA designation.
