Q

Rotor-to-stator air gap readings should be periodically taken for electrical generation equipment. What is the best tool to use to take these measurements?

🔍 Key Concepts

• Rotor-to-stator air gap and why consistent, accurate clearance is critical in generators and motors • Which tools are designed to measure small, narrow clearances rather than overall distances • How each listed tool is normally used in machinery work

💭 Think About

• Think about where the rotor and stator are located and how much physical access you actually have to the gap between them. Which tool can realistically fit in there? • Consider which of these tools can measure a thin, curved, hard‑to‑reach clearance safely without damaging the windings or metal surfaces. • Ask yourself: which tool is commonly used by mechanics to check very small gaps, such as valve clearances or bearing clearances?

✅ Before You Answer

• Verify which tool is specifically designed to measure small clearances rather than overall dimensions or movement. • Check whether the tool you’re considering can be used in tight, limited access without needing a straight, rigid line of sight. • Eliminate any tools that would require direct contact that might scratch or damage the rotor or stator surfaces or can’t follow the curve of the air gap.
