Thanks, interesting.
Your thoughts on flux capacitors ?

[Boaterguy]

I don't remember reading the word flux capacitor in there.
unless you are talking about it's age

Goes to show what's old terminology these days ... late 80's I think.. although there is some conjecture it was seen around '55 ...

[Boaterguy]

I understand the whole 88mph (kmh?) and then the flux capacitor goes of thing.
I just don't understand what you are referring to..

I wondering if it's possible to determine a motors wind by looking in the can? I have a leopard that nobody knows the wind on...

[Boaterguy]

if you see a point (usually with shrink wrap around it) where three wires meet inside the can, it's a y wind motor.
just by looking at the case you won't be able to determine unless it's written on it.

How do you know this?

Kv? spin at a known rpm and measure voltage between any 2 phase leads... do the math ..~=rpm/V
Delta/Wye ?.. unplug all leads to motor.. spin the rotor like heck for a few secs.. if this builds force against rotation then it is wye...spinning mags charge open coils, causes opposing force against mags... As D the charge is passed between all 3 winds thus no residual.

easy !

You've answered your own question...

cough.

Delta have 3 points where 3 meet.... Y only one.. the chance is 3:1 you get it wrong

[Boaterguy]

okay, the delta points go to the input wires, the wye is tree wires all connected to windings on the stator.

give up, dude....... you've nfi.. Im grumbly because your advice is poorly structured, problematic in execution.. and wrong !

Why do you (boaterguy) insist on chiming in on nearly every single thread with incorrect info? Seems every time you give "advice" someone need to come in a re-direct so the OP is getting the correct info.
I agree..... give up.
You need to learn through experience before you start giving out advice.

[LarrysDrifter]

Agree!!! Been happening a very long time. One can only hope a new boater with zero experience has not spent his money on your advise...
