B&R 8LSA35.DA060S100-3 400 VAC 6000 RPM Keyed Shaft Servo Motor 1.6 Nm

The B&R 8LSA35.DA060S100-3 is a high-speed 400 VAC servo motor intended for machine functions where rotary speed, fast direction changes and reliable mechanical power transfer are essential. Operating at a nominal speed of 6000 rpm, this motor is a suitable solution for compact production equipment that must maintain short cycle times without using a larger motor frame.

Its 14 mm keyed output shaft is the defining feature of this configuration. The keyway provides a positive connection between the motor and the driven component, helping transmit torque securely to timing pulleys, sprockets, gears or coupling hubs. This makes the motor particularly useful in belt-driven axes, indexing mechanisms and compact transport systems where repeated acceleration can place high demands on the shaft connection.

The motor is equipped with an ECI 1319 FS single-turn encoder using the EnDat 2.2 interface. This feedback arrangement supports controlled speed regulation and accurate positioning in matched B&R motion systems. The motor does not include a holding brake, so it is best suited to horizontal movement, rotary equipment or applications where the mechanical design independently supports the load during power-off conditions.

With a self-cooling construction, 1.60 Nm nominal torque and 94% efficiency, the 8LSA35.DA060S100-3 is well suited for replacement stock, machine refurbishment and service projects involving compatible high-speed servo axes. Check the original motor code carefully before replacement, especially the encoder version, shaft type, flange dimensions and brake requirement.

FAQ

Q: What makes this motor different from the S000 version?
A: The 8LSA35.DA060S100-3 uses a keyed shaft. The S000 version uses a smooth shaft. The keyed version is better suited to applications requiring a fixed mechanical connection to pulleys, gears or sprockets.

Q: Does this motor have a built-in holding brake?
A: No. This model is supplied without a holding brake.

Q: Is the motor suitable for vertical lifting applications?
A: It may be used only where the machine has a separate load-holding solution. For vertical axes requiring motor-based holding, a brake-equipped motor version is normally preferred.

Q: What encoder feedback is installed?
A: This model uses an ECI 1319 FS single-turn encoder with EnDat 2.2 communication.

Q: What is the rated operating speed?
A: The nominal speed is 6000 rpm.

Q: Can this model replace another 8LSA35 motor?
A: Replacement should be based on a full comparison of the motor code, rated speed, torque, shaft version, encoder interface, brake configuration, flange dimensions and drive parameter settings.
