Product Description:

The 8LSA46.DB030S000-3 synchronous motor is produced by B&R Automation as part of the 8LS Synchronous Motors series. It carries the 8LSA designation, meaning a standard build without reinforced bearings, and it uses a smooth shaft for direct coupling through a clamp collar or hub. With an integrated mounting flange, the motor can be fixed quickly to machine frames, making it suitable for feeder axes, carton erectors, or other packaging equipment that need repeatable motion in continuous production.

Its nominal operating point is 3000 rpm, a speed that matches the electronic commutation frequency delivered by the B&R drive so that full torque is available during standard duty cycles. The flange dimension of 100 mm matches the IEC mounting pattern and helps align the stator with gearboxes or coupling plates. A single-cable solution carries power, digital feedback, and 24 V auxiliary conductors within one hybrid lead, which simplifies routing and reduces cabinet penetrations. Because the motor relies on self-cooling with free air circulation, no external blower or liquid loop is required, but ambient airflow around the housing must be maintained. Position data are generated by an Inductive EnDat encoder that communicates through protocol version 2.2, permitting drive-based parameter storage and electronic nameplate functions.

Motion resolution is captured at 19/12 bit single-turn and multi-turn depth, giving 524,288 positions per turn and traceability across 4096 revs of travel without resetting. The assembly is shipped without a holding brake, so static load retention must be provided by the drive or by an external mechanical lock when power is removed. Internal construction follows Revision 3, indicating the winding insulation and connector layout used in this version. Length code 6 indicates the active stack height, and the absence of an oil seal shortens the axial length. The smooth shaft profile minimizes fretting during coupling.
