B&R 8LSA46.DB030S100-3 400VAC 3000RPM 7.7Nm Servo Motor EnDat Keyed Shaft

The B&R 8LSA46.DB030S100-3 is a 400 VAC synchronous servo motor for machine axes that require multi-turn absolute position feedback, a keyed shaft connection, and stable torque at 3000 rpm.

This motor delivers 7.700 Nm nominal torque and reaches up to 12000 rpm. The 19 mm keyed shaft is suited to couplings, timing-belt pulleys, gearboxes, and transmission components that require positive mechanical torque transfer.

The DB 2.2 inductive multi-turn EnDat encoder provides absolute feedback over multiple motor revolutions. This makes the motor suitable for positioning systems where the axis must retain multi-turn position information within the configured motion system.

This S100 configuration has no holding brake. It is appropriate for horizontal axes, supported rotary mechanisms, conveyor drives, and machine sections where an external mechanical holding method is not required after power removal.

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

Installation Notes

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

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

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