Delta or Wye

[drwayne]

Hey Boaterguy(Brydon)
What you said above was kind of correct..but there's much more to add for clarity, usability, and practicality... the answer that popped into your head was not a good solution.
Knowledge is a powerful thing, mate.... So too is knowing your limitations.

Knowledge comes from a lot of reading ( learn how others burnt things ), a lot of browning your own stuff ( learn from your own mistakes ) , and by joining a group of like minded people who challenge the boundaries of existing equipment ..

Dont go hide, mate ... hang around !
You read like an intelligent young bloke who has found a hobby that excites and entertains .. well done.... some folks go a whole life without direction or pursuits..

Experience the subject matter at hand, and become more articulate in your dispensation of that info.. and one day you may be heralded a demi-god of FE !

Right now, you're just green............

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 !

not sure i understand what you mean but,i sorta do lol, if that makes any sense haha! ill give it a shot, thanks =)

[dana]

so, i spun it for a bit and it really didnt seem to build up any tension against rotation…. but how can i be sure? do i have to take the endbell off?

[drwayne]

It wont build up wrist snapping tension, merely a physical resistance to rotation.
After the spin cycle, test the rotational drag against turning by hand slower..... 'tight' .. touch the 3 leads together, release, and spin again.. you would notice a marked reduction in 'drag' against the spin after the leads touch.

At uni 'naughty' ppl would charge up non-terminated Y wind motors for a nasty zap to the unwary ... the energy is stored in the coils.. and acts against rotation .

No, I was never naughty

im not noticing a difference. i did notice when you hold leads together and spin there is alot of tension

i just noticed steve posted the wind on this motor finally. its 3.5 d

[Steven Vaccaro]

Not sure what all the fuss is about. Get the boat on the water and test different timing values. If you always listen to what someone else says works, its most likely you will always come in 2nd place.

lesson#2.. how to determine if wind is delta...

[LarrysDrifter]

What Steve said. Half b.s. , half truth. Your own testing will determine success.

You can recognize the difference between a Delta or Wye winding just by looking at the back end of any motor. There aint no way to make any connection at the front so all motors can be easily recognized by doing a visual at the arse end. Here you go. First picture shows a Delta wind on a Neu, Second one is a Wye from a CC/Neu. You can clearly see that a Wye has 4 connections. And a Delta only has 3.

Does anyone know if Neu motors offers a configuration in both delta and wye like the bigger lehners do? If so do you think its worth it?
