B&R 8LSA25.R0060D300-3 400VAC 6000RPM 0.52Nm Servo Motor with 2.2Nm Brake

The B&R 8LSA25.R0060D300-3 is a compact 400 VAC synchronous servo motor for high-speed motion axes that require resolver feedback, positive shaft torque transmission, and holding capability after power removal.

This version runs at 6000 rpm nominal speed and delivers 0.520 Nm nominal torque. The keyed 9 mm shaft is suitable for coupling, pulley, timing-belt, and gearbox input connections where a smooth shaft would not provide the required mechanical engagement.

The integrated 2.20 Nm holding brake is intended to retain a stationary axis when drive power is removed. This makes the motor suitable for compact indexing units, small lifting mechanisms, servo feeders, and positioning modules where uncontrolled shaft movement must be avoided.

The R0 two-pole resolver provides robust feedback for compatible servo-drive systems. When replacing an installed motor, the resolver type, brake option, keyed shaft design, flange size, and centering dimensions should match the original motor.

This product is a synchronous servo motor only. It should not be described as a power supply, internal I/O module, X2X Link device, PLC, servo amplifier, or bus system component.

Installation Notes

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

The holding brake is designed to hold a stationary axis. It should not be used as the primary method for repeated dynamic stopping.

Use a compatible B&R servo drive and verify resolver feedback and brake wiring before commissioning.
