B&R 8LSA44.EA030D000-3 400VAC 3000RPM 4.62Nm Servo Motor EnDat Single Turn

The B&R 8LSA44.EA030D000-3 is a 400 VAC synchronous servo motor designed for machine axes that require stable torque at moderate operating speed, compact flange mounting, and single-turn absolute position feedback.

This motor provides 4.620 Nm nominal torque at 3000 rpm and can reach a maximum speed of 12000 rpm. The 19 mm smooth shaft is intended for clamping couplings, locking hubs, belt-drive pulleys, and accurately aligned transmission assemblies where torque is transferred by frictional shaft connection.

The EA inductive single-turn EnDat encoder provides rotor-position feedback for compatible servo drive systems. This configuration is suitable for applications that require accurate shaft position within one revolution but do not require multi-turn absolute position storage.

This D000 version does not include a holding brake. It is better suited to horizontal axes, supported rotary mechanisms, belt-driven units, and machine sections where an external mechanical holding method is not required after drive power is removed.

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

Installation Notes

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

This model has no holding brake. Do not use it on an unsupported vertical axis unless the machine includes an independent mechanical holding device.

Use a compatible servo drive and verify the EnDat encoder configuration, cable connection, motor parameters, and smooth-shaft coupling method before commissioning.

Ensure that the clamping coupling or locking hub is suitable for a 19 mm smooth shaft.
