🔍 Key Concepts

• Role of start (auxiliary) winding in single-phase motors • How a single-phase motor develops starting torque • Difference between starting current, running current, and starting voltage

💭 Think About

• Ask yourself: What problem does a single-phase motor have when it is at rest, and how does the auxiliary winding help solve that problem? • Which winding (main or auxiliary) is usually taken out of the circuit after the motor comes up to speed, and what does that tell you about its primary job? • If the main winding failed, would the auxiliary winding alone be designed to run the motor continuously, or just to help it get moving?

✅ Before You Answer

• Verify the definition of auxiliary (start) winding in a split-phase motor • Check which option describes a function needed only during starting, not during normal running • Eliminate options that confuse limiting/increasing voltage or current with creating the necessary starting torque.
