What stator configuration results when the winding ends are paired together to form a closed loop?

• A. Wye connected stator
• B. Delta connected stator
• C. Open-delta stator
• D. Star-delta hybrid stator

Answer: (B)

Pairing winding ends to form a closed loop describes a delta-connected stator. In a delta, the three windings are connected end-to-end around the stator so they form a loop with three junctions that become the external line terminals. There’s no neutral point in this setup, which is what characterizes the delta arrangement. In contrast, a wye (star) connection ties one end of each winding to a common neutral point and brings the other ends out to the line terminals, so the windings don’t form a closed loop around the stator. An open-delta would have one winding missing, breaking the closed loop, and a star-delta hybrid isn’t a standard closed-loop configuration.
