The B&R 8LSA46.R2030D200-3 is a 400 VAC synchronous servo motor designed for medium-torque machine axes that require stable speed control, controlled positioning, and holding capability after drive power is removed.
This 3000 rpm motor provides 7.700 Nm nominal torque and 10.000 Nm stall torque. The integrated 8.00 Nm holding brake makes it suitable for axes that must remain in position during a controlled stop or power-off condition, including vertical handling units, indexing mechanisms, feeders, and compact transfer equipment.
This version uses an R2 two-pole resolver for motor feedback. The resolver configuration is important when replacing an existing motor because the connected servo drive must be configured for the same feedback system.
The motor has a smooth 19 mm shaft and a 100 mm square flange. It is a synchronous servo motor only and should not be described as a servo drive, PLC, power supply, bus module, or general-purpose induction motor.

Installation Notes
Confirm the original motor model, resolver type, brake rating, shaft dimensions, centering diameter, and flange size before replacement.
The 8 Nm brake is intended to hold a stationary axis. It should not be used as the primary method for repeated dynamic braking.
Use a compatible B&R servo drive and matching motor cable. Verify resolver feedback settings and brake wiring before commissioning.
