B&R 8LSA35.DA030S100-3 3000 RPM 2.1 Nm Key Shaft Synchronous Servo Motor

The B&R 8LSA35.DA030S100-3 is a 400 VAC synchronous servo motor developed for compact machine axes requiring controlled speed, repeatable positioning and stable torque performance. With a rated speed of 3000 rpm and a nominal torque of 2.10 Nm, it is suitable for industrial automation equipment where accurate movement and consistent production cycles are required.

This configuration uses a keyed 14 mm shaft rather than a smooth shaft. The key shaft helps provide a positive mechanical connection when the motor is installed with matched gears, pulleys, timing belt assemblies, chain sprockets or other transmission components. It is especially suitable for applications where shaft slip must be minimized during acceleration and reversing movement.

The motor uses a DA 2.2 inductive 32-line single-turn encoder with EnDat 2.2 communication. This feedback arrangement supports dependable motion control when paired with compatible B&R servo drive systems. The single-cable connection design helps simplify machine wiring by combining motor power and feedback connections into one cable route.

This version is supplied without a holding brake, making it practical for horizontal axes, rotary modules, conveyor positioning mechanisms and applications where the machine structure or an external device provides the required holding function. Before replacement or retrofit installation, verify the original shaft type, encoder version, connection configuration, drive settings and mechanical mounting dimensions.

FAQ

Q: Does the B&R 8LSA35.DA030S100-3 include a holding brake?
A: No. This model is supplied without a holding brake and is generally suitable for horizontal axes or systems with another holding method.

Q: What is the difference between 8LSA35.DA030S100-3 and 8LSA35.DA030S000-3?
A: The S100 version uses a keyed shaft, while the S000 version uses a smooth shaft. Both versions have the same 3000 rpm nominal speed, 2.10 Nm nominal torque and no holding brake.

Q: What is the rated speed of this servo motor?
A: The nominal speed is 3000 rpm. The maximum mechanical speed is 9000 rpm.

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

Q: What shaft type is used on this motor?
A: The motor has a keyed shaft with a 14 mm k6 diameter and 30 mm shaft length.

Q: Can this servo motor be used as a replacement unit?
A: Yes, provided that the original motor uses compatible voltage, torque, encoder feedback, shaft type, connector arrangement, mounting dimensions and drive parameters.
