8LSA54.R0030D000-0 by B & R Automation

B & R Automation produces the 8LSA54.R0030D000-0 within its 8LS Synchronous Motors series. Carrying the 8LSA designation, this standard model omits reinforced bearings but still provides radial load capacity suitable for belt drives and direct couplings. It attaches through a mounting flange and mates to machine frames with minimal alignment work. When paired with an ACOPOS drive, the unit supplies regulated torque and speed profiles for pick-and-place axes, feeder tables, and indexing stations in automated production lines.

The motor uses a 142 mm square flange that aligns the stator housing and provides four through-holes for rigid attachment. Internally, length code 4 indicates the lamination stack depth, balancing torque output against moment of inertia. Under nominal excitation, the rotor reaches 3000 rpm, a speed range that suits mid-range conveyors and screw actuators without overspeeding standard couplings. Rotor position is measured by a resolver, which provides robust feedback and high noise immunity in environments with switching frequencies or welding currents. Thermal energy is removed by self-cooling through free air circulation, so airflow around the housing is sufficient to maintain winding temperature. Repeatability is supported by 10 arcmin positioning accuracy, which helps limit cumulative error across multi-axis systems.

Power and signal leads enter through an angled swivel connection that can be rotated after installation to improve cable routing, and the locking connector simplifies disconnection when the motor must be removed. Motion is transferred through a smooth shaft, favoring backlash-free clamp hubs or shrink discs over keyed components. The stator is wound for three-phase synchronous operation, so the drive must supply sinusoidal phase currents with vector control. An internal holding brake and an oil seal are not included, so the motor is best suited for dry, clean areas where axial thrust and fluid ingress are limited.
