So bear with me as this just a silly idea but I was wondering if it would work while I'm waiting for the proper 3-phase regulator on the slow boat from China.
I have a LC gy6 (2006 CPI GTR 150cc) with a 3phase stator. The only wires from the stator are the 3 yellow AC wires. Could I connect each yellow wire to a seperate little regulator(I have 3 of those square little 4 pin regulators sitting around) and feed the red wires out to the battery. Would thos setup work to charge the battery?
Craziness I know but I was just wondering.

Technically the setup may work, but the setup could overcharge the battery and damage it.

So it wouldn't damage the stator?
How could the setup overcharge if each regulator is outputting correct voltage?

So it wouldn't damage the stator? How could the setup overcharge if each regulator is outputting correct voltage? With the 3 phase (3 yellow wire connection) stator, each wire will have electricity going from the stator to R/R. I think it's around 14volts. But don't quote me on that. One job of the R/R is to take those 3 streams of electricity and funnel them into one consistent stream as an output. So if you have 3 R/R directing electricity to the battery, I would think that would be 3 times the electricity. It's a very interesting concept, but practically it makes no sense to wire a scooter that way. It would create a whole spider webs mess of wires and a pain in the butt finding mounting points for the 3 R/Rs. Plus you would have 2 additional points of possible failure in your electrical system. |

Isnt rule: wired in series increases voltage, wired in parallel increase amps?
Yes I know it woould be a mess, and i have the correct regulator on the way. This is a thought exercise and possibly an experiment.

It would be an interesting experiment and is very thought provoking. But I would defeat the purpose of a 3 wave setup.

take a video and name it watch a 3phase stator smoke 3 single phase regulators.

too much pressure/voltage and too much excess power= too much heat.

So...do you mean the voltage into the battery would be multiplied by 3(14 volts x 3 = 42 volts?)

You could just not use a regulator till the new one comes in. Use the kickstarter instead of the electric since the battery won't be recharging, save electric starts for emergency use until you have a new regulator and can charge your battery again. You could also make sure to charge it every night until the new regulator comes in as well. That's what I did once. Sure you won't have lights, but you will still get around, just don't drive at night.

First, my experience. I have made three phase regulators with discrete components for my scooters which worked quite well for many miles. Here is a very basic overview.
Before you regulate the voltage you need to connect each stator wire to its own bridge rectifier.
You connect all the rectifier positive output wires together in one bundle and all the negative output wires together in another bundle.
You connect the negative wire bundle to the frame.
At this point you have unregulated DC current with an open circuit (no load) voltage in the 70 volt range.
You then connect the positive wire bundle to a SHUNT REGULATOR. This type of regulator regulates the load by grounding out excess current to maintain voltage control. All the current has to go somewhere, use another kind of regulator and you are likely to fry the stator. The shunt regulator ground wire is grounded to the frame and the positive wire lead to the battery.
Be sure to mount the rectifiers and regulator to a substantial heat sink.
Now, for the regulator, are you ready for power transistors, resistors, and zener diodes -- maybe an op-amp or two?
Spend time in electrical and electronic self study before you attempt this project or find a buddy who can guide you as you do it. It was a fascinating area of study for me and it took six months and several tries to get my first successful regulator built.

I've waited two plus weeks for parts........ That's why you need a back up ride so you don't have to go thru this stuff. After reading this thread it seems to wait a few more days is the best answer, unless you're -bent on making this work. Then I wish you luck, that's how we learn things.
