Product Description:
The 8LSA46.R0030D200-0 is a servo motor built by B&R Automation for the 8LS Synchronous Motors series. Carrying the 8LSA designation, the unit has a standard build without reinforced bearings, making it suitable for applications that subject the shaft to moderate side loads rather than extreme belt tension. A compact flange interface simplifies integration with gearboxes or direct-drive stations. The motor supplies accurately regulated torque so plant controllers can synchronize index tables, feeders, or small gantry axes without mechanical cams.
The motor reaches a rated speed of 3000 rpm, giving machine designers headroom for high cycle frequencies before gearing. Position feedback is delivered by a resolver, whose analog sine-cosine output remains stable under shock and heat. A square flange measuring 100 mm provides the bolt pattern and concentric pilot used to center the housing. Power and signal lines exit through an angled swivel connection that pivots to relieve strain on the installed connector. Thermal energy is removed through self-cooling with free air circulation, so suitable enclosure ventilation must be provided. Length code 6 places the active stack in the middle of the available range, balancing continuous torque against inertia. Axial accuracy is maintained within 10 arcmin, supporting moderate positioning tasks on pickers or labeling heads. The motor has no oil seal, which makes it best suited to environments without coolant spray or excessive dust.
A standard holding brake is integrated to lock the rotor whenever supply power is disabled, preventing load drift on vertical slides or lead-screw lifts. The output end has a smooth shaft, which accommodates backlash-free clamping hubs or shrink discs without additional machining. Internally, the stator uses a three-phase synchronous winding, enabling sinusoidal commutation with balanced phase currents suited for vector-controlled drives. The brake can hold a stationary load when motor torque is unavailable. Clamping connections distribute force evenly around the shaft and avoid the play associated with keyed couplings. Balanced phase currents also support smooth torque production during controlled acceleration and deceleration.
