B&R 8LSA35.DA060S300-3 6000 RPM 1.6 Nm Keyed Shaft Servo Motor with Brake

The B&R 8LSA35.DA060S300-3 is a compact high-speed servo motor created for industrial machines that combine rapid rotational movement with secure torque transmission and axis holding capability. Its 6000 rpm nominal speed supports fast production cycles, while the 1.60 Nm rated torque provides controlled performance for smaller motion axes, transfer mechanisms and driven processing stations.

This configuration is designed around a keyed output shaft and an integrated holding brake. The 14 mm keyed shaft is suitable for mechanical assemblies that require a fixed connection between the motor and a pulley, sprocket, gear hub or coupling. It helps reduce the possibility of shaft slip in applications with frequent starts, reversals and high-speed indexing movement.

A 4.00 Nm holding brake is included to retain the machine position when servo power is removed. This makes the motor a suitable option for equipment with elevated loads, vertical mechanisms or machine sections where the axis should remain stationary during shutdown or maintenance. The brake should be used for holding duty rather than repeated dynamic braking.

The DA 2.2 inductive 32-line single-turn encoder with EnDat 2.2 communication provides motion feedback for compatible B&R servo drive systems. The single-cable connection arrangement reduces the number of cable runs between the motor and drive, helping simplify installation in enclosed machinery where routing space is limited.

For replacement or retrofit work, the complete motor code should be checked against the installed unit. Pay particular attention to rated speed, holding brake requirement, encoder interface, keyed shaft version, cable connector arrangement and servo drive parameters.

FAQ

Q: Does the B&R 8LSA35.DA060S300-3 include a holding brake?
A: Yes. This motor includes an integrated 4.00 Nm holding brake for retaining the axis position when power is removed.

Q: Is the shaft smooth or keyed?
A: This configuration is identified as a keyed shaft version. The 14 mm shaft is intended for use with compatible pulleys, gears, sprockets or couplings that require positive torque transfer.

Q: What is the nominal operating speed?
A: The nominal speed is 6000 rpm, and the maximum mechanical speed is 9000 rpm.

Q: What feedback device is used in this motor?
A: It uses a DA 2.2 inductive 32-line single-turn encoder with EnDat 2.2 communication.

Q: Can the holding brake be used for frequent stopping?
A: No. The brake is primarily intended to hold the axis after power removal. Normal deceleration and dynamic stopping should be controlled by the servo drive and machine design.

Q: Can this motor replace another 8LSA35 servo motor?
A: It may be used as a replacement only after confirming the complete part number, speed rating, torque requirement, shaft configuration, brake option, encoder interface, mounting dimensions and drive settings.
