🔍 Key Concepts

• Starting torque vs. running torque for different single‑phase induction motors • Role of a capacitor in improving phase shift and starting torque • Basic characteristics of shaded pole, resistance start, and capacitor motors

💭 Think About

• Rank the four motor types from lowest to highest starting torque based on how effectively they create a rotating magnetic field at start • Think about which design provides the largest phase shift and strongest auxiliary winding during starting • Ask yourself: which motor type is most commonly used when you must start a heavy load, like a compressor or pump?

✅ Before You Answer

• Verify which motor types use a start capacitor that is only in the circuit during starting • Check which motor has only a weak auxiliary winding or simple shading coil, giving inherently low starting torque • Confirm which design is normally used for light-duty appliances (like small fans) versus heavier-duty machinery that needs strong starting torque
