B&R 8LSAA2.D8045S200-3 400VAC Servo Motor 4500RPM 1.27Nm with 3.2Nm Brake

The B&R 8LSAA2.D8045S200-3 is a compact 400 VAC synchronous servo motor for industrial motion systems that require fast rotational speed, controlled positioning, and a holding brake for stationary axis retention.

This model combines a 4500 rpm nominal speed with 1.270 Nm nominal torque in a 70 mm flange format. Its integrated 3.20 Nm holding brake is suitable for vertical axes, indexing units, feeders, and compact positioning mechanisms where the motor must remain secured after power removal.

The motor uses an ECI 1119 FS EnDat 2.2 single-turn encoder for position feedback and includes a smooth 14 mm shaft. The angled swivel single-cable connector helps simplify routing in compact machine layouts.

This product is a synchronous servo motor. It is not a power supply, bus module, encoder accessory, PLC, or standalone motor controller.
