if the shunt regulator is controlling the voltage at the preferred level and also becoming hot, then that's a good sign, it means it's working as per its specifications. Thank you sir for your explanation. dear sir could you help me to modify your circuit ( made with tl431 and tip 147) to put n-mosfet thanks. could you point me to what to check to sort this problem out. Also, chances are that you have had some start-up or voltage issues. The following post of a full wave motorcycle shunt regulator circuit was requested by Mr.Michael. Anyway, in other case you can skip it or move to Step 3. To know if it fits you have to look at the generic regulator, if it has one or two red, one or two black and three "other-colored" wires (pink, brown etc. This eliminates the rising current in the armature and protects the winding from heating up. All because of one little diode, two of the three generator windings are converted into unnecessary stuff. I only ever read that the regulator runs cooler but nothing mentions effects on the stator. The process repeats at a very rapid speed, keeping the output voltage marked with +/- at a constant level determined by the setting of R2/Z1 and R3/R4. I made a meter long wires, so after I figured out that it becomes barely warm it moved under the seat. Regulator/rectifier units vary from model to model, and manufacturer to manufacturer. Gxcdizx Universal Mosfet regulator rectifier 50 AMP & Upgrade kit Replaces SHINDENGEN FH020AA ATV Motorcycle Snowmobile PWC $32.00 Only 10 left in stock - order soon. The above principle utilizes voltage inhibition technique of the excess voltage instead of shunting it to ground, thus saves precious power and also helps to control global warming in some way. Share it with us! as i see there is already a zener in series with the transistor base (i'm going to use mosfet instead of tip transistor). Lamberts Bikes Motorcycle Part Wiring Diagrams. Same thing here, only it's very fast. Same will be the situation if n-mosfet is used. Question Regulator rectifier diagram here you are at our site this is images about regulator rectifier diagram posted by maria nieto in wiring category on may 08 2019. I put the cooling fan too but the result is the same. This schematic will perfectly work on any motorcycle with three-phase generator, for instance CBR* and others. Not yet, you can take the help of this design, it's similar and also correct: I don't know much about alternator criticality so I won't comment until I research the whole thing…. you can tweak the 3k3 resistor value to achieve the correct output. It controls every aspect of charging and power supply systems, so it must be very powerful to support plenty of electrical devices found in today's motorcycle. I have made one using tl431 ic type. The rectifier actually converts the power from AC to DC, while the regulator keeps the power level (voltage) from going above the 13.8 -14.5 volts needed to power a standard 12 volt battery. check shortcuts between each phase and the "+" must be infinite or MOhm resistance, no shortcuts. Sir, my motorcycle need 3 phase shunt motorcycle regulator. Normally the process of shunting is done by grounding the excess voltage, just as zener diodes do in electronic circuits. An even simpler motorcycle shunt regulator using the shunt regulator IC TL431 can be witnessed below, the 3k3 resistor can eb tweaked to chnage the output voltage to the most favorable level. Auto VR adjusts the voltage on the field winding of the generator. I gave my radiator to the miler, who cut the ribs, but the radiator needed much work after that because the cutout was very coarse. Second picture shows a graph in the form of "boobs" - this is the only survived phase. you can try adding a finned type heatsink to the transistor for enabling a better heat control, such as this: diyaudioprojects.com/Testeq/Dummy-Speaker-Load/VHS-95-Heat-Sink.jpg. If not, than this is a sure way to kill its brain! If you polished the heat-sink and applied the thermal paste, than the heat will transfer to heat-sink, spread and everything will be ok. LOOK VERY CAREFUL how i connected the "stabilitron" Zenner Diode, note the mark on it, it must look towards BTA bus. So this is actually my first attempt to use them. And motorcycle shunt relay controller works so: when the voltage across the winding of the stator winding is exceeded it shunts the generator winding, not giving the voltage to rise above provisions, and this is due to the fact that as the causative agent in the motorcycle a permanent magnet is used and it requires no excitation. In looking again at the datasheet, I see that Gate current is plus or minus 10 nano Amps. If it does not work: somewhere screwed up or bought the faulty chip. adjust the preset such that mosfet gate receives around 9V at the desired trip point…for example if the regulation point is 14V, adjust the preset to produce 9V at the gate for the mentioned regulation limit, make sure to use a 8V zener in series with the mosfet gate, anode towards gate. Thanks a lot Mr. Swagatam for the simpler design.. but if the output after rectifier in idle condition more than 25 volt dc, I think when the bike running will produce more voltage and current. The R1/R2 should be adjusted such that the transistor conducts only at 7 V. Hello, I was wondering if this circuit also works when one side of the light coil is connected to ground. The result must be the same. Hello aytac, you can try the folowing design: dear sir many thanks… i did this circuit as same as in shematic but rarely i have fixit 3.5volts but without circuit i can reach in same rpm of wind turbine around 36volts. The shunt stabilizer makes excess voltage "bypass the consumer". For single phase alternators, the 6 diode bridge rectifier could be replaced with a 4 diode bridge rectifier as shown in the following diagram: it's the one with 741 circuit not the lm431, at 18V the the output from the 741 is the same as the input but after the gate zener it is now become 9v at 18v input which i'm using 8v zener for the gate mosfet. This schematic will perfectly work on any motorcycle with three-phase generator, for instance CBR* and others. is this for the first last diagram or the second one? 10 months ago. The problem is caused bu the epoxy at the time it process a chemical reaction. Single-core and multi-core copper wires 2-2.5 square mm, Huge or big radiator, the higher the ribs - the better it will work. When the voltage is less than you need, a zener diode does not conduct current, all the current goes to the consumer. The circuitry used here is rather simple. 15V 10 Amp Voltage Regulator Circuit Using IC LM196 the following article will probably assist you on the points''Voltage Regulator rectifier units Oregon Motorcycle Parts April 29th, 2018 - For bikes with electromagnet alternators the rectifier and voltage regulator built into one unit''how to install brake lights on a classic bike • matchless Hi Chito, yes it can be easily done by disabling one of the main CDI wires through the wireless relay. Apply thermal paste, this is also VERY important. It is worth noting that we speak of the shunt relay controller. The moment the high voltage reaches R3, which happens to be the sensing input of the opamp, pin#3 of the IC senses an increased voltage. When you are supeshure in your layout you can cut out the ribs for parts. Pure epoxy and hardener together, mix it well, follow instructions on the box or wherever they are. In certain cases, when there is an fatal error made during mounting and soldering of the relay, the VR can issue a 300V! I have access to a multimeter. Required fields are marked *. If an ordinary battery is acid, its rate of charge lays within 13.8 - 14.5 V. If the battery is gel, the rate is 14.5-15.5 V. Different sources say different. First design may harm your stator and rectifier. In experiments with the running motor better do NOT connect on-board electric network as a load because in some weird cases of force majeure there is a possibility to burn out all the electronics on the bike. Does not work: looking for faulty BTA semistors - change with a new one. Generally, you need to find a zener diode so that the whole scheme gave the needed voltage. 1 / 19. Triple Maintenance Manual A 2 Stroke Motorcycle. Basically the designs are like higher power zener diodes, which will never allow the applied voltage to go higher than the specified rating. It also becomes very fluent unlike it is at the start of reaction. Can I post an electrical diagram of my test circuit? Provided below is an online PDF document for Lamberts Bikes 4 pin regulator rectifier wiring diagram. That was another issue with one of the others. if you have not adjusted the LM431 output at 18V then it could be strange…because the LM431 output at the gate will regulate the output at the same level….so if it's 9V at the gate, the output should be also approximately 9V regardless of the input. So the current is water flow rate, and the voltage - water level in the channel. Do these operations with all three phases (all three bridges that is). On the picture, perhaps, the most complete regulator circuit is shown that can be found in the manual on Japanese motorcycles. The problem is my battery is always no powerfull and i have to charge it manually. Can the old rectifier be bypassed? Make a very good bath in your heat sink. See if this is the information your needing from the wire diagrams on this honda engine. (That's why I recommend to by a couple of these). This is not an Alternator model. First of all, check the integrity of the diode bridges, this poor thing suffer most. For fans speed up the process: adding more thickener to glue, epoxy resin may lose their dielectric properties. i want to fix output 12v my op-amp is lm339p many thanks. Check if your wiring is correct again. The motorcycle rectifier/regulator current output: Analog & Mixed-Signal Design: 10: Jul 13, 2014: B: Understanding Motorcycle Regulator / Rectifier: Homework Help: 1: Sep 21, 2012: K: Fixing a motorcycle rectifier/regulator. ), then it's likely our case. I hope the circuit design above solve my motorcycle problem. But try not to overheat. Electric current is, as we know from school physics course, a "directional movement of electrons". Replace the voltage regulator if the reading is higher or lower than the 13.5 to 14.5 volt range to prevent insufficient or excessive charging. DC current does not. Hi, the op amp shunt regulator will also work with an N channel, just make sure the op amp output turns ON at around 12 V. You can put an LED/1k across pin6 and ground to confirm the results.

I used a 13V zenner and had 13.5-14V output, if you'll use 14V diode, you'll probably get 14.3-15V. In general, everything is simple, but there is a serious problem - a rectifying diode bridge is very heavily loaded and richly heated, because they are forced to overcome all the current produced by the generator through themselves. To understand what it is, imagine that your wire is the channel, and the current - water flowing over it. If you continue to use this site we will assume that you are happy with it. The moment T1 switches OFF, voltage at the junction of R3/R4 reverts to the original condition, that is the voltage here now drops below the reference level......this instantly activates the opamp output with a low logic signal which in turn switches ON T1 back into action. The most common failure of VR is the failure of one of the diodes, ie breakdown of any diode. Can anyone advise if it's possible to verify the correct generator/stator wires? At different RPM voltage must not vary significantly +/- 0.5V, this will be quite normal. The question is.. can the 3 phase motorcycle shunt regulator in the above article is able to handling the high voltage at the input of regulator and then stabilize the voltage too? But measuring the output voltage you are unlikely to find the correct voltage. Julian, I'll update a new design soon in the above article….the existing design might be incorrect. Replacing the rectifier, which converts the alternating current (AC) from your motorcycle's stator/alternator to direct current (DC) before recharging the battery, is also recommended at this time. Now, check that your output wires do not shortcut, do not lay on the bike frame, do not lay on your hands etc. In this video, I probably demonstrate a method to troubleshoot and repair a 12 volt charging system's voltage rectifier regulator. I am referring to R4 in the first diagram and 4K7 resistor for the second diagram. Auto VR is a stabilizer. check leads in both directions from phase to plus contact. regulator/rectifier. It seems there's maybe a 'in' and an 'out' and a 3rd wire going to the regulator as well. I have tip36 transistor and many 2SA1494 power transistor at home. Some of text parts are alike to DIY forums due to that it was discussed by me and/or other people in the process of making this project. Thanks very much AkosN4! Same for the triac marking.
