🔍 Key Concepts

• Single-phase motors reverse by changing the relative phase of the main (run) and auxiliary (start) windings • Reversing must swap the connections of only one complete winding, not both at the same time • Look closely at how leads T1–T4 (main) and T5–T8 (auxiliary) are shown in all four diagrams A–D

💭 Think About

• If you interchange L1 and L2, what happens to the direction of current in the main and auxiliary windings relative to each other? Does that change the rotating field? • Which pair of leads in the options belong to the same winding so that swapping them would reverse just that winding? • Trace the circuit in one figure and then imagine swapping each proposed pair of leads in turn. For which option does the main winding stay the same, while the auxiliary winding’s polarity reverses?

✅ Before You Answer

• Identify clearly which terminals are the main winding leads and which are the auxiliary/start winding leads in the illustration • Verify that your chosen pair of leads, when interchanged, reverses only one winding, leaving the other winding’s connection to L1 and L2 unchanged • Confirm that interchanging your chosen leads would not short out the supply or bypass the centrifugal switch / starting relay / capacitors shown in the circuits
