B&R 8LSA35.EA030D200-3 400VAC 3000RPM Servo Motor 2.1Nm with 4Nm Holding Brake

The B&R 8LSA35.EA030D200-3 is a compact 400 VAC synchronous servo motor designed for industrial axes that require stable rotational control and reliable holding performance when the machine is stopped.

This version operates at a nominal speed of 3000 rpm and delivers 2.100 Nm nominal torque. Its integrated 4.00 Nm holding brake makes it suitable for positioning axes that must remain secured after drive power is removed, such as vertical mechanisms, feeders, indexers, and compact handling units.

The motor uses an ECI 1319 EnDat 2.1 single-turn encoder for position feedback. Its smooth 14 mm shaft and 91.3 mm square flange support replacement use in existing 8LS servo installations where the mechanical interface, brake option, and encoder configuration must match the original motor.

This product is a synchronous servo motor. It should not be described as a power supply, PLC module, bus device, standalone controller, or variable frequency drive.

Installation Notes

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

This model includes a holding brake, but the brake is intended for holding a stationary axis rather than routine dynamic braking.

Use a compatible B&R servo drive and matching motor cable. Verify motor parameters in the drive configuration before commissioning.
