ELECTRIC TRANSMISSION DELTA /WYE and SERIE/PAPALLEL stator

Gui, have you a link for the Pheobus rally? Can't find one on Google.

[GUI13]

ouuuups ! rally phebus http://rallyesolaire.eu/

[paultrafalgar]

Thanks, Gui, and here's what Google translated that into:

A solar rally, why?
The sun is tested constantly by satellites and observatoiresterrestres to better understand its operation and its influence on our climate.
The earth is a solar collector in space and our daily life depends on it. People naturally use solar energy for hundreds of thousands of years. Now came the time when they rediscovered as a source of clean, renewable energy.
For satellites and spacecraft, this energy is immediately seen as the most cost-effective. The will of the founding organizers of the rally, 'ENSEEIHT Phébus Ariège, the CNRS and the Cité de l'espace, is to be the core issues related to environmental quality, which led them to create this draft Solar Rally in 2000.
The technology required to make a solar vehicle are often researched and developments which the space is a precursor.
By organizing this European Solar Rally, we want to offer the public a better understanding of the challenges and enormous potential energy that represents for us the nearest star to Earth, the Sun!
From 28 to 1 June 2009

So you see your Engish is better than Google's translation of French!

Nice bike!

Where do you put the batteries?

[GUI13]

in my backpack !

[karma]

hay it works nice work gui13. i never got around to trying it. now that i see the results, i think its worth the extra work.

cheers

gui just wondering if the windings are all in parallel like inpic below, or maybe some in series? could change motor rpm etc by changing how the coils are connected also

Bonjour à tous.
Je vous lis souvent grâce à un traducteur car je suis nul en Anglais !
Je met un lien pour Doctorbass sur une discussion ou il y a des renseignements sur les moteurs 9 Continent.

Je suis très intéressé par : ELECTRIC TRANSMISSION Video DELTA / WYE With 9 continent mais je n’y comprend pas grand choses. Je vais voir avec Gui13 et d’autres s’ils peuvent m’expliquer le principe ?

Salutations amicales


Hello to all.
I often read through a translator because I am no one in English!
I put a link to a discussion on Doctorbass or there is information on engines Continent 9.

I am very interested in: ELECTRIC TRANSMISSION Video DELTA / WYE With 9 continent, but I did not understand much. I will do with Gui13 and others if they can explain the principle?

Kind regards

The attachment fp parallsmall.jpg is no longer available

I also had this idea but the major problem is the qty of wires that goes out of the motor that is too high!! 10 to 12 wires!! instead of 6 like the delta WYE

Also the ratio would be 2 instead of 1.73 for the delta wye. so the current demand would be twice

See the drawing i did few month ago:

Doc

[tostino]

How possible/easy would this be to do with a Bafang motor? Does it have enough room to have all the wires going out the side of the case?

[wasp]

could i bypass the extra wires and switch by just wiring delta?

[Doctorbass]

could i bypass the extra wires and switch by just wiring delta?

yes.

In delta mode the current will increase to 1.73x so the controller may heat a bit more pay attention to that!

thx Doc if i do overheat i'll step up to infinion and limit amps with ca

[karma]

ill say one thing running the extra phase wires was a pain in the arse but i pulled it off

[Doctorbass]

Great!!.. what is the wire gauge you used? (to have 6 phase wire out of this bolt axel?

Did you tried the delta mode?

Can you take more photo (close up to the phase wire input and output from the axel + closeup on the winding ire soldered?

Doc

[wasp]

nice karma
any video comlng

[karma]

ya just did a test im uploading them now. i will say one thing. when you see it in person the speeds insane

[wasp]

can't wait...36v or 48v

[karma]

70v and i found out my wheel needs truing talk about out of ballance. you will see in the vids.

cheers

[Doctorbass]

Hey Karma... Where is your delta/wye golden motor vid 4 ??

Interesting video exemple about the Delta/WYE.. Thanks

Doc

[karma]

there taking forever to load im sure you will like this one

cheers

I'm curious if it's not more out of balance....would the valve weight unbalance a wheel? (I would be curious to try to balance my wheel at 80KM/H)


This vibration is doing something to efficiency for sure...

Robin

[Doctorbass]

Ah haaa!!.. that's perfect!!

Now who will try that first on the road

Gui... YOU... Me... Almassi?

(please be carefull with this Delta mode... The parasitic current stay in the winding loop and is more subject to overload mosfets withg some noise..

So let's try step by step first at low speed... I dont want to someone blow his controller because of that... and having a controller mosfet short at 60kmh or + is,,,,, VERY BAD.. it can freeze the wheel like you can not imagine!.. like a short circuit direct on the phase wire.. a 100% regen in a second!!!


So let's not blow this great idea and let's be carefull to preserve this great idea intact...

why not start with few video with 10kmh.. then 20kmh.. etc....

Who know.. up to 90-100kmh could be fun if nothing blow... ...but only as fast as a 5305 can do

Doc

[wasp]

looked fast karma's bike
reminds me of the kick a 2 stroke does in the powerband
delta=powerband....hang on delta's bout to kick in lol...

[karma]

hehe ya i did a on road test just in delta. this setup will only work good if it kickes in at maximum rpm. so im going with doctorbase's relay idea. would be nice to have a turbo button
