🔍 Key Concepts

• Split-phase induction motor construction – difference between start (auxiliary) winding and run (main) winding • Starting switch / centrifugal switch – what it is supposed to do once the motor comes up to speed • Effects of keeping a high-resistance starting winding energized during normal running

💭 Think About

• Think about what the starting winding is designed for: is it built for continuous duty or just for the brief starting interval? • If the start winding never cuts out, what happens to its current and temperature when the motor is running at or near full speed? • Look at each option: which one directly relates to electrical/thermal stress on a winding versus mechanical speed behavior?

✅ Before You Answer

• Verify that the starting winding has higher resistance and is not rated for continuous operation. • Consider whether overspeed is a normal failure mode for induction motors connected to a constant-frequency supply. • Ask yourself which component would most likely be damaged if excess current flows for too long in a small auxiliary winding.
