Jerry:
Thanks for the message, but I do not know what is the meaning of "Jerry Phased", I can not correlate the wiring to standard electric motors terminology.
Neither I can correlate to Jerry Blades.
I am familiar with all GE ECM Brushless motors and I have samples of all of them, even others not yet available in the market because they are new.
What I am interested is the changes or modifications done and the reason for such changes, the wind mills and the operational RPM.
A 1/2 HP in hydro use can supply around 240 watts, the 3/4 HP, 340 to 360 watts and the 1 HP 440 to 480 watts.
This power is in constant defined RPM and loaded for maximum equivalent MPPT power transfer with minimum internal losses.
The Units for maximum power in wind mill service should be able to have such peak powers available in hydro if the Wind mill operates in the 1200 RPM or so.
We avoid internal circulating currents by not re-wiring the coils and allowing the wind mill to produce its natural high voltage and either use transformers or doing a rectification and convert the voltage down as needed, which in wind mill usage it may not be possible if the frequency is too low, (starting conditions).
The motors have 6 poles and may be usable with transformers around 300 RPM or a bit less. (30 Hz operation).
It seems that very few have used them for wind power generation and I was trying to pick their ideas and efforts to save some time and decision making for small wind mills to be built in Center and South America and in Africa for people that do not have any other sources for electric power available to them, being Solar Panels too a high price for the system.
Thanks to all that have supplied information and still waiting for those that have used them and have not yet replied to my message.
