8LSA44.R2030D200-3 by B & R Automation

The 8LSA44.R2030D200-3 belongs to the 8LS Synchronous Motors series from B&R Automation. It is intended for positioning and velocity tasks in automated machinery where compact rotary motion is necessary. The A-variant configuration omits reinforced bearings, and its 8LSA designation aligns with the standard build used in this series. This makes the motor suitable for compact axes where available installation space is limited. It can be used on compact transfer units, indexing devices, and other machine axes that need precise rotary motion in a limited envelope.

Internally, the motor relies on self-cooling through free circulation, so ambient air removes winding heat without auxiliary fans. During continuous duty, it sustains a rated speed of 3000 rpm, matching drive controllers that output 50 Hz electrical frequency. Rotor position is reported through a resolver, which delivers analog sine-cosine feedback that tolerates electrical noise. This feedback format remains common in industrial motion systems that favor robust signal transmission. A flange dimension of 100 mm sets the mounting interface, and wiring is performed through a field-replaceable connector with an angled swivel orientation to ease routing inside tight cabinets. The stator's three coils form a three-phase synchronous machine, and length code 4 indicates the active stack depth that balances torque with inertia. Product revision 3 identifies the current mechanical update level. Because no oil seal is present, the shaft zone requires an external barrier if fluids are anticipated.

For controlled stops, a standard holding brake is integrated and energized by the drive to secure the load whenever power is removed. Positional repeatability is limited to 6 arcmin, which satisfies general-purpose indexing where servo accuracy tighter than one tenth of a degree is unnecessary. A smooth shaft simplifies coupling with compression hubs or collets and avoids keyway stress concentrations. The motor is suitable for conveyors, pick-and-place heads, and format adjustment axes.
