Application of single and three phase induction motor ukrian dating
If we tried to connect X5 X6 X4 to L1 L2 L3 (along with X1 X2 X3), we still have the same rotation but I don't think it will work because X1-X2 now peaks at the same time as X5-X6 (rather than at same time as X4-X5 as designed).

The two winding halves behave as transformers with the three phases interconnected in wye.* Homer Wisdom - "Operator, Give me the number for 911" * How would it work to induce a voltage in the second wye by applying dc to the first one?I am used to seeing 9 lead wye connected dual voltage motors, so 6 circuits 1-4,2-5,3-6,7-(10),8-(11),9-(12) (10,11,12 permanently connected wye) So if you apply dc to lead 1 and lead 2 of one wye and measure with a volt meter on second wye to find the lead pair with most induced voltage with the correct polarity, that should be the parallel circuit 7-8 shouldn't it.If these are the same phase pairs, you will be adding voltages which are in-phase or 180 out and the resulting voltage x1 to x4 will go to 0 or will double.
In that case you have found that pair x1/x2 is equal to pair x4/x5 (if voltage goes to zero) or is equal to pair x5/x4 (if voltage doubles).
I would try it if it were mine, and then bump it, but you're on you own,'cause I don't know if it will work. Sounds odd, but if true, thenthe hardest part of the job has been done already (findingthe polarity of the second set).
