B&R 8LSAA4.D8045S200-3 400VAC 4500RPM 2.8Nm Servo Motor with 3.2Nm Brake

The B&R 8LSAA4.D8045S200-3 is a 400 VAC synchronous servo motor designed for compact machine axes that require single-turn absolute feedback and a holding brake.

This motor operates at a nominal speed of 4500 rpm and delivers 2.800 Nm nominal torque. Its smooth 14 mm shaft is suitable for clamping couplings, friction-locking hubs, and accurately aligned direct-drive assemblies.

The integrated 3.20 Nm holding brake is intended to retain a stopped axis after drive power is removed. This configuration is suitable for compact vertical mechanisms, transfer modules, indexed fixtures, and machine sections where uncontrolled shaft movement is not acceptable.

The ECI 1119 FS EnDat 2.2 single-turn encoder provides position feedback for compatible servo drive systems. Before replacement, confirm the motor model, encoder type, shaft design, brake requirement, flange size, and centering dimensions.

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

Installation Notes

Confirm the original motor model, encoder type, brake requirement, shaft diameter, flange size, and centering diameter before replacement.

The holding brake is designed to keep a stationary axis in position. It should not be used as the primary method for repeated dynamic braking.

Use a compatible servo drive and verify encoder wiring, brake wiring, cable type, and machine parameter settings before commissioning.
