For those who have worked with three phase power, these terms are readily understood.

But, for our use, that Wye and Delta configuration has been decided by the motor mfg when the motor was built. It could be changed afterward, but doing so would be dealing with real short motor magnet wires, and the problems associated with reconnecting them in the different configuration.

I did some of that Wye Delta stuff with those www.gobrushless.com motors I wound up some 10 years ago. (Still have those motors)
