Q

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

🔍 Key Concepts

• Induction motor construction – relationship between stator, rotor, and the air gap between them • Feeler gage use – what kind of quantity can a feeler gage actually measure? (mechanical vs electrical) • Effects of changing air gap – what part of the motor would cause the air gap to change over time?

💭 Think About

• Ask yourself: Does a feeler gage check an electrical characteristic (current, power factor, losses) or a physical clearance? • Which of the answer choices is directly related to a change in the physical spacing between rotor and stator? • If the rotor slowly shifts off-center during operation, what component’s condition would most likely be changing?

✅ Before You Answer

• Verify which options describe electrical performance (current, losses, power factor) versus mechanical condition (alignment, support, wear). • Confirm what a stator-to-rotor air gap actually is and how it would change if a support component starts to wear. • Check that the quantity you select is something that can reasonably be inferred from a periodic mechanical clearance check with a feeler gage, not from electrical test instruments.
