Hi Jack

I'm not sure why it's called that. Maybe because it evolved from the 12N14P dLRK Delta scheme. I think I first saw it on Ralph Okon's old website, so I suspect that he has developed this version.

It is my favourite too, because it makes Delta termination very easy. I've wound lots of motors like that.

See how it compares to the 'standard' 12N14P dLRK Delta scheme below.

Hi
Scheme of post #74 is convenient for delta(triangle) connecting
Scheme of post #76 is convenient for star(Y) connecting
due to locations of exit or connected wires

Hi Louis
You mean like this? It is the same as in post #76, just with Wye termination.

Since those winds I have obtained a stand alone scope, and every new wind I do is measured to check waveform outcome. Also in case of delta winds I investigate the open delta waveform.
