BRM stands for which term?

• A. Bearing Rotor Monitoring
• B. Bowed Rotor Motoring
• C. Basic Rotor Maintenance
• D. Bowed Rotor Maneuver

Answer: (B)

BRM refers to Bowed Rotor Motoring, a term used to describe the condition where the rotor bows while it is being driven by an external motor rather than generating power. The idea behind this is to test how the rotor behaves under motoring conditions to detect abnormal bowing, rubbing, or clearance issues between the rotor and surrounding components. This helps technicians identify misalignment, excessive bearing loads, or thermal/distortion problems that wouldn’t be as evident when the rotor is simply idling or acting as a generator. The other options describe more generic concepts or different activities (monitoring bearings, basic maintenance, or a maneuver) that don’t capture the specific diagnostic scenario of a rotor bowing under motored drive.
