Wondering what is inside this kind of regulator and how it differs from those commonly used HALF wave regulator, you are in luck for i have the time and resources to open up this donor regulator. it took me hours of heating up, scraping the coating to expose the main board and parts.
Here it is.
Patience is the key when doing this kind of hobby.
HOURS later,
back view
And the schematic of this board
Single Phase Shunt Regulator (full wave)
They are almost identical, but as i have said, the regulator above is a five wire type, the schematic shown on left is a four pin type. The difference, the circuit within the link is always connected to the battery thus leakage is present. while as this regulator has a wire (BLACK) that is connected after the ignition switch and not directly to the battery.
It was used for one reason:
1. when ignition off, monitoring circuit of the schematic is disabled, no current will be taken from the battery when stored, or park.
We have a saying " its better to have more than to have enough" This particular five wire regulators can be used on four wire type. just connect the black and red together..
By looking at the schematic, and comparing it to my previous post of voltage regulators, it is almost identical, with the design, and only component values are different. C1, R1, Q1, D1, and R3 compromising the sensing and regulating circuit, whereas D2,D3, Q2 and Q3 are the shunting components of the stator winding.
D4 to D7 are your rectifiers that converts the AC coming from the stator to DC for charging your battery. With the values as shown, the output of this regulator is 14.4 at 5000rpm. You can modify this circuit for your intended application, to output 15 volts rather than 14.4 for quick charging of your battery when there are too much load on your system, by altering D1, to 13 volts rather than 12.6 volts..
This system is Stator dependent...meaning, this can't output more power on what your stator can give, all charging system power rely on your stator max output...
Note: further again..the generator to be used here do not touch the ground or not connected to any ground.
The circuit before scr, can I replace with simple LM7815?
ReplyDeleteThx.
I dont think so, i know what you are thinking, the circuit you are trying to replace is the monitoring circuit. It function like a level meter of the battery so that when the battery voltage drop to a calculated level within that circuit, It will shutdown the SCR from clipping the stator winding, and when it do sense that the battery is at the maximum voltage , that is again sense by that circuit, it will trigger the SCR shunting the winding to ground so that minimal current will be feed to the battery..LM7815 will never i think will do both..
DeleteSir i give u part list of gy6 fullwave regulator
DeleteHow many SCR to fit if the winding of stator are 3 wire? Is six? Or you have a formula or an alternative circuit?
ReplyDeleteHi, what is the brand name of this regulator? Does it have any identifying marks outside the case of this module? Please let me know so that when i buy a full wave regulator, this is the one i'm going to ask at the store. Thanks
ReplyDeleteHave you seen any versions of the fullwave reg/rect with additional outputs?
ReplyDeleteI've found one with the four usual wires (R,G,W,Y) plus an additional red/white wire, which looks to be used to power the auto-choke/enricher on some models. I'm wondering if that is an output (12vdc?) that is only active while the engine is running, and could be used to power headlights, either directly or through a relay, such that they're only on when the engine is running.
I've also seen some with 6 wires (R,G,B,Y,Pink,White) where I suspect that it may be the same as you show here plus an "engine running" output on the white wire.
I have a motorcycle with no battery I can't connect the 5 wire regulator to stator because I confused the stator wire is 4 wire black white yellow and red my question is how to wire stator to regulator?
ReplyDeletese me ocurre sustituir los scr por un solo triac.
ReplyDeleteGood day sir, me I know if how many Amps the Positive of this regulator?
ReplyDeleteGood day sir, may I know if how many Amps the Positive of this regulator?
ReplyDeleteplease i need the reference of tis regulator, please, i nedd purchase one

is this a gy6-125 4pin rectifier that can be used as a full wave rectifier for mio?
ReplyDeleteGud day how wire this rectifier with 5 pins in honda tmx 155 with 4 pins ...pls help badly needed tnx in advance
ReplyDeleteAlbert
ReplyDeletekindly search for the schematic diagram of the 5 pin regulator here. What you looking for was inside an article here.
Good eve sir,pwedi ba ang bridge na 1000v 35a ipalit ko sa mb254?

ReplyDeleteThe Bridge Diode MB254? I tried to find them but it is very hard to find in my country, Indonesia. can it be replaced with other series?
ReplyDeleteIdk if this is a stupid question or what. What will happen if I use this on a halfwave stator?
ReplyDeletePaul Eugene Delfin Bundoc
ReplyDeleteIf so happen you haven't read the difference between half wave and full wave in concern with the connection. A short summary gives that HALF uses Ground as one of the source of the Stator winding, while as full wave is indirectly connected to ground. search the whole blog about half and full wave differences.
Hi sir paano po magfullwave ng stator ng honda supremo
ReplyDeleteHonda supremo is a 3 phase starter coil is in Wye "Y" winding it has a different regulator find the diagram of a 3 phase motorcycle voltage regulator it uses 3 scr
DeleteSir Paano po magfullwave ng stator ng honda supremo ,thanx
ReplyDeleteis this applicable to 6v system ? by altering with 5.6V zener ?
ReplyDeleteMy device has 8 wires. y,y,y,g,g,r,b,w. My bike is a cb 500 all plugs and sockets are gone. Wiring is from scratch. Wires need to be identified.
ReplyDeleteDo not be misguided by the fact that if u have a big bike or very large displacement motorcycle. They are not either HALF WAVE SINGLE PHASE or FULL WAVE SINGLE PHASE but A 3 PHASE motorcycle charging system. This is very visible with 3 IDENTICAL COLOR of wire coming out from the generator side, irregardless of other color which are RED and BLACK or any other color for positive and negative output to battery. Mostly they are 3 yellow or 3 white color of wire and that is an automatic 3 phase system.
DeleteSir.. Ano kaya problema bkit ng. Shoshort circuit yung scr?..pag mataas b n value n diode malaki b ang epekto nito?gmit ko 5408 diode
ReplyDeleteRecheck you built unit...wag nyo palitan ng hindi nakasaad na part..dahil yang regulator na yan gumagana nung binaklas...so dapat pag bumuo kayo gagana din assuming na modified nyo na stator mula half wave to full wave...
ReplyDeletehow many amps of brigde type diode will be use in this fullwave rectifier and what is the value of Q1,Q2,Q3?
ReplyDeleteHello. I always wondered the effects of using switch-mode with PFC: Will the output voltage be more stable in idle, in single cylinder bikes? Will it outputs more voltage in idle? Will it generate less heat? Will the engine gain power at low or high rpm?
ReplyDelete@GIORGOS
ReplyDeletefirst of all, the voltage regulator of motorcycle is always dependent on the engine revolution or RPM. Using switchmode with fluctuating voltages is of no use. If you want more stable output, aside from the full wave which is more efficient than HALF WAVE. If you can fit a 3 phase system on your current configuration, then that is the best. Unfortunately. Three phase system is used on sports bike 400cc up displacement and bigger sizes. Three phase still works even on IDLE and output more current than half and full wave which are both SINGLE PHASES type of regulation.
I always talk about thee phase generator. Mopeds have.
ReplyDeleteKey points that you missed:
PFC
SMPS (full wave, to buffer capacitor, with PFC, to switch mode circuit, to output capacitors, to output).
I thought about smps because:
Linear regulators doesn't work at low rpm, low voltage differences (you must have input 15 volts to output 13).
SMPS can work. Also the first buffer capacitor would help smoothing the input voltage. Also smps is more efficient than linear, thus no thermal waste, maybe more power?
Psu from imac can work at 220v, 110v even at brown-out conditions, so a not stable input shouldn't be a problem. Plan B might be to calibrate the output at low rpm, so to have lower voltage, but stable.
Giorgos
ReplyDeleteIf you can make it work, then that will be good news. Funny thing is why up until now no motorcycle manufacturers especially luxury ones did not even try other types of voltage regulations on their product line up aside from the three phase system.
I been thinking also those Gasoline powered generator AVC generators, but with the way the generator speed is fixed on a certain RPM.
How about MPPT solar panel regulators.
There is actually so much happening on a motorcycle stator aside from source of electricity to charge the battery. Something is needed to control the output by struggling it to the point that it will not create very high voltages at the possible highest RPM of the motorcycle can handle. If something fails on the electronic side. It will be a very very bad news. You can even power an incandescent light on that Stator without the voltage regulator easily.
Let me know how your SMPS idea will perform on your plan. Thank you.
