When the stator ends are connected to form a delta configuration, what configuration is formed?

• A. Delta connected stator
• B. Open-delta stator
• C. Star configuration
• D. Wye winding pattern

Answer: (A)

Connecting the stator windings into a closed loop around the circumference creates a delta arrangement. In this setup each winding is connected between two line terminals, so there is no neutral point and the three external connections form a triangle. The line voltage is applied directly across each winding in a delta, which is different from a star (wye) connection where one end of every winding is tied together at a neutral point and the other ends go to the lines. An open-delta is a partial triangle formed by only two windings, not a complete delta. So forming a delta configuration means the stator is delta-connected.
