8LSA43.R0030C600-0 by B & R Automation

The 8LSA43.R0030C600-0 is a three-phase synchronous motor manufactured by B & R Automation within the 8LS Synchronous Motors series. Identified by the internal 8LSA designation, this unit supplies rotational power to indexing tables, linear stages, and other motion axes in industrial automation. Its electromagnetic circuit is designed for constant speed tracking of the supply frequency, making it suitable for closed-loop servo applications that call for accurate position and velocity control.

At a rated speed of 3000 rpm, the motor can be integrated with standard 1:1 couplings without step-down gearing. The resolver feedback provides commutation and position data with an angular precision of 10 arcmin, ensuring deterministic control loops in multi-axis gantries. A flange dimension of 100 mm aligns with IEC mounting faces and offers repeatable mechanical registration to the machine frame. Thermal management uses a self-cooling method that relies on free air circulation around the housing, eliminating external fans and minimizing wiring. Length code 3 indicates a medium stator stack that balances torque output with envelope size, while the mounting flange provides a simple face-mount interface to machinery. There is no holding brake, so static loads must be secured by the drive or external locks.

Power and feedback leads exit through a top connector, so cable routing can follow vertical cabinet raceways without extra bends. The smooth shaft simplifies coupling with backlash-free clamping hubs, and an oil seal protects the internal bearings from coolant spray common to machining centers. Because the motor is delivered in a standard build without reinforced bearings, radial load capacity should be checked carefully when belt tension or overhung loads are present. The straight connector orientation keeps overall length short and helps maintain compact cable routing near the machine frame.
