Castle Neu Motor winds

[Sammus]

Apparently its more efficient. Not sure of the physics behind it exactly, but I know that with a wye wind only 2 coils are energized at a given time, with a delta wind all 3 are - not a real strong basis for my claim I guess, just a gut feeling plus some 'I've read something like it somewhere' kind of things in the back of my head telling me to think it :p
