Q

What is being detected by checking the stator-to-rotor air gap clearance in an induction motor periodically with a feeler gage?

🔍 Key Concepts

• Induction motor construction – relationship between rotor, stator, bearings, and air gap • Purpose of the air gap between stator and rotor and what happens if it changes • How bearing condition or mechanical alignment might affect rotor position

💭 Think About

• If the air gap between stator and rotor becomes uneven or too small on one side, what mechanical problem in the motor could cause that? • Which of the choices would actually change the physical distance between the stator and rotor, rather than just electrical characteristics? • Think about what a feeler gage measures: is it used for electrical properties or physical clearances?

✅ Before You Answer

• Confirm that a feeler gage is a tool for measuring mechanical clearance, not electrical parameters • Ask which choice would directly affect rotor position relative to the stator and thus the air gap • Eliminate any options that deal mainly with electrical or magnetic strength rather than physical spacing
