Alternator stator: Triangle connection or star connection
« on: July 31, 2008, 21:31:41 pm »
Hi guys
after one year and half studying studying reading and reading  with lot of ideas ==> time to jump to water!
Bought today and alternator+ electrical motor to spin it .

All the schematics show star connection , (were in practice I should see just 1 wire wdge going to diodes)
Here im my alternator i see 3 group of 2 wires which looks to me triangle connection of the stator winding.
the question:

Should I disconnect the triangle winding connection and re connect as star connection or ...who cares ...does matter to much..?

Thank you fellows

Hey Jose421

I run a stock 1969 Chevy alternator, Without built in regulator. No modifications.  ;D

Hi Spike

Thanks .

Do you know which stator winding configuration do you have in you alternator triangle or star?

H James

Thank you !
Your answers was very clear !.
Now Ihave leart : what you call in US delta connection I have been taught in engineering  and called triangle connection and what you call whye connection
I call star connection.

Yes My alternator do not have midle point neutral but has 3 groups of 2 windings edges together so that apparently is a DELTA conneaction,
high amps but relative low voltage.

Well
I will  disconnectwindings and connect them Whye


Thank you James

 ;D Here is a basic Delco alternator wiring  ;D

Minus the regulator of coarse.

Hi James

correct me if am wrong:
If i leave the delta connection, would I need to higher RPM in order to get the same voltage comparing to Y connection?
 In others words , can i get the same results as using Y conection?

Thank you
Yossi

Hi James
Thank you,
Forgot to mention : the regulator is out , so you right ! no limit (almost..) to high voltage and amperage stator can climb so I must be carefull.

Good you pay me attention to that!!

Heyy  I have a question for you :

You said you activate your alternator with a 5HP electrical engine, that is huge energy ~ 4000watts!!

When you are experementing WFC ,do you monitor the torque or the amparage of that 5HP motor ?
That motor is input energy, so it is relevant to know its input wattage to know where you are in term of efficiency.

Many Thanks
Yossi

Hi James

Thank you again .

I will start experimenting WFC by the end of that week where 2 issues have to be accomplished:

1) I have sent a mechanical drawing for  a shaft interconnection between Alternator to 12VDC motor
2) Windings 3 kinds of Bi filar coils ( 300 turns, 500 turns and 1000 turns).

So far I will eexperiment using 1 SS tube .
If things will looks good I will add more tube and report to forum.


BTW  and that is for all of us:


I have a theory/assumption why is to difficult to reach the 700% and up efficiecy :
 
Most of us are using square waves. There is aproblem with that and that is  because square waves, according to Fourrier transfer series , contains endless sinewave at different frequencies and harmonies AND one of them hits!!

Lets compare that to an automatic machine gun vs a sharp shooter rifle with telescopic lens:


The target:

One tiny bird at 2 miles distances zig zaging at 150Km per hour  ( in the WFC the  resonant frequency is constanlty and widly changing!!!)

With the automatic machine gun, no need to be accurate you pull the trigger , and one of the bullet will hit.

[but you waisted 200 bullets!!]


Now Sharp shhoter rifle with telescopic lens waist an accurate single bullet!!


Here is where the secret of 700% efficiency is found with the WFC


How to be lock constanly on the wild changing resonance  frequency using harmonic sine wave and not square wave.

Best regards
Good luck to all of us with the hard project
