In theoretical examples, 3-phase circuits are shown as either Wye or Delta type. Wye obviously containing a neutral line.
Recently I watched a Youtube video where the uploader re-purposed an old motor and turned it into a generator. The motor (from what I can tell) is wired in a 3-phase Wye type setup (circled in red). See figure 1 below:
Note: The figure resembles the actual model. There were no other connectors shown aside from the X,Y,Z as shown above.
EDIT: We are assuming the motor has now been converted and is being used as a generator.
Scenario 1: Now lets pretend lines X,Y,Z are led off and connected to a Delta-type transformer.
- Q1: How does this complete the circuit if there is no neutral or ground? Will the current return path occur during the negative cycling of the other two phases?
