8LSA35.E3030D200-0 by B & R Automation

The 8LSA35.E3030D200-0 is a three-phase synchronous motor manufactured by B & R Automation and supplied in the 8LS Synchronous Motors series. Within the type code, it carries the designation 8LSA and a length code of 5, which indicates its stack height within the family. Built as a standard configuration with no reinforced bearing, the unit is intended for industrial servo axes where compact dimensions and reliable torque production are critical. By converting stator current directly into precise rotary motion, it lets packaging, material-handling, and assembly machines maintain repeatable cycle times while following digital motion profiles. The synchronous design also supports accurate speed regulation and stable positioning when it is paired with a compatible servo inverter.

At a rated speed of 3000 rpm, the rotor can supply continuous motion without breaching the thermal envelope of its housing. The mounting face provides a pilot diameter of 91.3 mm, giving a fixed reference when centering the frame against gearboxes or adapter plates. Cabling exits through an angled swivel connection, a layout that simplifies routing in tight spaces while reducing strain on the connector hardware. Heat is removed by a self-cooling design that relies on free air circulation, so no external fan or liquid circuit is required. A standard holding brake locks the rotor to prevent unwanted movement during power-off states or safety stops.

The mechanical interface uses a mounting flange, allowing direct fastening to equipment frames without foot adapters. Output torque is delivered through a smooth shaft, so couplings or pulleys must clamp on the journal rather than use a key. Because there is no oil seal at the shaft exit, the motor should be kept away from environments with spray-borne lubricants. This shaft arrangement is better suited to clean, dry installations where contaminants are limited. Electrically, its winding arrangement follows a three-phase synchronous topology, enabling closed-loop operation with servo inverters for accurate position and velocity control.
