Question 1 of 27070

Rotor-to-stator air gap readings should be taken on electrical generation equipment periodically. Why is this necessary? check machine efficiency determine the need for cleaning

🔍 Key Concepts

• Rotor-to-stator air gap and why it matters in generators and motors • How mechanical clearances affect electrical performance vs. physical safety/reliability • The difference between efficiency issues and maintenance/cleaning issues in rotating machinery

💭 Think About

• Ask yourself: If the air gap changes slightly, what is the most immediate technical consequence: change in electrical efficiency, risk of contact/damage, or buildup of dirt? • Consider why an engineer would schedule periodic measurements instead of just relying on performance tests—what are they trying to catch before damage occurs? • Think about whether cleaning needs are better detected by inspection of surfaces/filters/ventilation, or by measuring a precise mechanical clearance like the air gap.

✅ Before You Answer

• Verify which problem a changing air gap directly signals: misalignment, bearing wear, rotor movement, or dirt accumulation. • Decide whether machine efficiency is normally evaluated through electrical/operational tests (voltage, current, power factor, temperature) or through a mechanical gap measurement. • Consider whether a need for cleaning would typically be identified by visual inspection/contamination checks rather than an air gap micrometer reading.
