B&R 8LSAA4.D9045S000-3 400VAC 4500RPM 2.8Nm Servo Motor EnDat Multi Turn

The B&R 8LSAA4.D9045S000-3 is a 400 VAC synchronous servo motor for machine axes that require multi-turn absolute feedback, a smooth shaft connection, and compact installation dimensions.

This motor operates at 4500 rpm nominal speed and provides 2.800 Nm nominal torque. The smooth 14 mm shaft is suitable for clamping couplings, shrink discs, friction-locking hubs, and direct mechanical connections where torque is transmitted without a shaft key.

The D9 2.2 inductive multi-turn EnDat encoder provides absolute position feedback across multiple shaft revolutions. This makes the configuration suitable for axes where multi-turn position information is required during controlled startup and machine reference procedures.

This S000 version does not include a holding brake. It is intended for horizontal axes, supported rotary mechanisms, belt-driven assemblies, and other motion systems where an independent mechanical holding method is not required after power removal.

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

Installation Notes

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

This model does not include a holding brake. Do not use it on an unsupported vertical axis unless the machine has an independent mechanical holding device.

Use a compatible B&R servo drive and confirm the EnDat multi-turn encoder configuration before commissioning.

Check the smooth-shaft coupling method and ensure correct shaft clamping torque during installation.
