B&R 8LSA46.DA030S300-3 400VAC 3000RPM 7.7Nm Servo Motor with 8Nm Brake

The B&R 8LSA46.DA030S300-3 is a 400 VAC synchronous servo motor designed for machine axes that require a keyed mechanical connection, single-turn absolute feedback, and load holding after drive power is removed.

This model delivers 7.700 Nm nominal torque at 3000 rpm. The 19 mm keyed shaft is suitable for couplings, timing-belt pulleys, gearboxes, rotary tables, and other transmission components where torque must be transferred through a positive shaft connection.

The integrated 8.00 Nm holding brake is intended to keep a stationary axis in position after a controlled stop or power-off condition. It is suitable for vertical mechanisms, transfer units, indexing assemblies, and machine sections where uncontrolled axis movement must be avoided.

The DA 2.2 inductive 32-line single-turn EnDat encoder provides position feedback for compatible servo systems. This configuration is intended for applications that require shaft position information within one motor revolution and use machine referencing during startup.

This product is a synchronous servo motor only. It should not be described as a PLC, servo drive, power supply module, X2X Link device, internal I/O module, or gearbox.

Installation Notes

Confirm the original motor model, encoder type, brake configuration, shaft-key dimensions, flange size, centering diameter, and cable arrangement before replacement.

The holding brake is intended to hold a stopped axis. It should not be used as the main method for repeated dynamic braking.

Use a compatible servo drive and verify encoder wiring, brake wiring, motor parameters, and shaft coupling alignment before commissioning.

Do not mix this model with 8LSA46.DA060S100-3 or 8LSA46.DA060S300-3 because those models have different nominal speed and torque ratings.
