B&R 8MSA3L.R0-67 Self-Cooled Resolver Servo Motor
A frame-size 3, long-body 8MS synchronous servo motor with resolver feedback for established B&R motion systems.
Product Profile
8MSA3L.R0-67 is a B&R three-phase synchronous motor from the 8MS family. The designation identifies construction type A, frame-size 3, long body and resolver feedback; the complete suffix must be preserved for winding and option compatibility.
The motor is self-cooled and intended for closed-loop operation with a compatible B&R servo drive and correctly matched motor cable.

System Role
- Resolver feedback for robust closed-loop position and speed control.
- Self-cooled motor construction without a separate fan.
- Frame-size 3 mechanical envelope with a long stator body.
- Option-sensitive type code covering winding and mechanical execution.
Compatibility
- Match the complete 8MSA3L.R0-67 designation, not only the 8MSA3 frame group.
- Confirm resolver interface, winding code, connector orientation, brake and shaft options.
- Verify the connected ACOPOS drive and cable part numbers before energizing the axis.
Applications
- Legacy B&R motion axes in packaging, handling and machine automation.
- Replacement of an identical 8MS motor when the drive setup and cable system remain documented.
- Planned retrofit studies where motor inertia, mounting and feedback must be preserved.
FAQ
Can another 8MSA3L motor directly replace 8MSA3L.R0-67?
Not automatically. The feedback, winding, connector, brake and shaft options encoded by the full designation must match.
What feedback system is used by 8MSA3L.R0-67?
The R0 designation identifies resolver feedback.
What mechanical data should be checked for 8MSA3L.R0-67?
Verify flange, centering diameter, shaft, key, connector direction and installed body clearance.
Should servo parameters be changed after replacing 8MSA3L.R0-67 with the same model?
Restore and verify the approved axis parameters, then complete the machine commissioning procedure.
Which cables should accompany an 8MSA3L.R0-67 enquiry?
Provide the installed power and resolver cable part numbers plus photographs of both motor connectors.
What tests are required after fitting 8MSA3L.R0-67?
Check insulation, brake if fitted, resolver polarity, direction, homing, tuning, limits and loaded motion.
