Q

Rotor-to-stator air gap readings should be taken on electrical generation machinery periodically. Why is this so? determine the need for cleaning check the condition of the bearings

🔍 Key Concepts

• Purpose of rotor-to-stator air gap measurements in generators • Relationship between air gap uniformity and bearing condition • How contamination/dirt affects air gap readings and generator performance

💭 Think About

• If the air gap changes from one reading to the next, what mechanical condition in the machine could cause that change? • Does dirt or the need for cleaning usually change the size of the air gap, or does it mainly affect other performance factors? • Which of the two listed reasons is directly monitored by measuring a distance between moving and stationary parts?

✅ Before You Answer

• Clarify what an air gap reading actually measures (distance vs. cleanliness). • Think about how worn or damaged bearings would physically affect the rotor position relative to the stator. • Decide whether cleanliness is normally checked by distance measurements or by inspection/other indicators (heat, vibration, etc.).
