Neu - Y versus D windings

I wonder if anyone can directly answer the original question, comparing the two similar KV motors...

Too bad we can't try on the motors like you do shoes or something...would be nice to have the ideal fit as opposed to making whatever you buy work.

I found this online:

"A motor with windings in delta configuration gives low torque at low rpm, but can give higher top rpm. Wye configuration gives high torque at low rpm, but not as high top rpm."

From this article: http://en.wikipedia.org/wiki/Brushle...electric_motor

And another one here: http://www.patentstorm.us/patents/64...scription.html

"Accordingly, in an application requiring high torque at a low speed, the motor is permanently configured in the wye configuration. Consequently, a conventional brushless motor design requires a compromise between high torque at a low speed and low torque at a high speed."

So..... my conclusion:
From the links BrianG provided and the articles above, there can be a comparison between Y and D for a given winding. But for a D and Y that come out with very close KV ratings, the difference is probably pretty negligible.
