Q

Why should rotor-to-stator air gap readings be taken periodically on electrical generation equipment?

🔍 Key Concepts

• Air gap between rotor and stator in generators and motors • How bearing wear or misalignment affects rotor position • Why mechanical clearances are critical to prevent contact between rotating and stationary parts

💭 Think About

• Which option is most directly related to keeping the rotor centered and safely separated from the stator? • If the air gap becomes uneven, what mechanical component or condition is most likely responsible? • Which choices talk about electrical performance versus mechanical alignment, and which is more closely tied to an air gap measurement?

✅ Before You Answer

• Identify which choices deal with mechanical alignment/position rather than electrical efficiency or insulation treatment • Ask yourself: if the air gap changes, which listed condition would that most clearly indicate? • Eliminate any options that do not involve rotor position, stator position, or parts that control their relative spacing
