Product Description:

The 8LSA46.DA030S000-3 is a three-phase synchronous motor manufactured by B&R Automation for the 8LS Synchronous Motors series. The 8LSA designation indicates the standard construction without reinforced bearings, which helps keep the rotor light and responsive during acceleration. This makes the motor suitable for pick-and-place units, transfer axes, and gantries that need quick starts and repeatable motion. When used with a matching servo drive, it supplies controlled torque and speed for automated assembly, packaging, and material-handling equipment.

The motor reaches a rated speed of 3000 rpm, enabling direct coupling to conveyor rolls and moderate-inertia tools. Thermal energy is removed through self-cooling with free circulation, so no external fan or coolant loop is required during continuous operation. Wiring uses a single-cable hybrid solution that routes power and sensor conductors through a molded rear connector, which helps reduce cable volume and cabinet clutter. A square face with a 100 mm flange dimension aligns the motor to the machine frame, while a precision pilot recess supports concentric coupling installation. Shaft position is measured by inductive EnDat feedback, which sends absolute position data to the drive for controlled motion.

The feedback channel conforms to EnDat 2.2 and provides 19 single-turn bits for precise indexing tasks. Because the encoder is single-turn, the drive reads absolute position within one mechanical revolution rather than tracking multiple turns internally. The motor has no mechanical brake, so holding torque at standstill must come from the drive or an external clamping device. Torque is transmitted through a smooth shaft, and the housing mounts by a mounting flange used with this motor length. Product revision 3 and the lack of an oil seal reduce drag at the shaft and suit clean, dry operating environments.
