Nice info left. Thank You

Thanks I was shocked to see such a thing on that. I never knew till then.

Good man, David !. Consider, sealing anything up, with JB WELD. After your completely sure, it makes power consistently. GLUE THEM SOLID, so no more problems. IF i was a designer, engineer, i would put most all stuff, on armature, in epoxy cement. Modules, like in your alternator voltage regulator. No vibration, would destroy anything !

It is a brush type or brushless. Brush check voltage regulator. Brushless check capacity.

Good point

Brushless is correct

Its not a very big generator that's for sure. 1000 watt.

There's actually 3 sets of windings. First, the main output winding. Next a small set of excitation windings that create a small AC charge induced from residual magnetism of the main winding.This is then induced to a small set of field windings , which is converted to DC by the diodes, causing our main winding excitation and output.

No idea sorry

Great! Thank you very much!

There are four primary ways that ferromagnetic materials can be magnetized. They include exposure to heat, using an external magnetic field, stroking or electromagnetism. With these methods, ferromagnetic objects will produce their own magnetic field Your welcome.

Hard to say what the problem is it matters to which type you have some have voltage regulator and some only use a capacitor.

@@MrDoingEverything this has the AVR, and I believe that may be the issue. I ordered a new one, and it will be here tomorrow so I'm gonna change it and hope for the best.

Could be the same reason as in the video. Sounds like half the windings lost the connection which is giving half the voltage. My best guess.

Perhaps the capacitor unless there are other types of electronics controlling it. Then the problem would be in there somewhere. Like a brain box of some sort.

there are a total of 4 electrical components in the entire generator - 2 windings, a 12 uf capacitor and a circuit breaker. both windings are to spec, the cap reads 12.35 uf and the circuit breaker shows continuity. when inserting probes into the receptacle, the ciol winding reads 1 ohm (to spec). the field excitation winding with the capacitor in the loop reads 1.75 uf (inductor-capacitor circuit). I don't know what else to check.....

Are you sure its spinning at needed rpm or maybe the keyway sheared were it joins to the motor. The motor may run good but where it connects to the armature it may have lost a solid connection and not spinning as fast or tight as it needs to be.

Check the Voltage Regulator. I find that after they fail they may produce a small amount of voltage.

no research them out

Probably exciter winding and rectifier.

Yeah

Slow and carefully are always the best methods

In this case you need to include an AVR circuit with rectifier stage to stabilize the power output and prevent peaks or drops i guess.

Good Question! The rotor needs a DC voltage to create the magnetic field thus the diode is there. With a 2000 watt brushless unit here the bridge rectifier is just used as a Big diode. ie the two AC leads are cut off the plastic bridge diode package. The rotor here has the 2 rotor coils in parallel connected to the + and - terminals of the bridge.This affair has a 15 K ohm resistor across it for surges. When used this way you have two pairs of diodes in series, then the each is in parallel. So like 1.2 volts drop DC ie 2 diode drops instead of one. This is probably just done for cost and packaging, one has this tiny brick shaped diode box to fit in a hole and goop in place. Many diodes on brushless generators are a single diode on bigger generators. The brushless generator like in this video has also an extra winding in the stator that connects to a capacitor. My 2000 watt unit has a 20uF cap. When running and outputting 120 volts the cap voltage on mine is like 189 volts. If this cap is gone/removed you get about 4 volts across the cap wires and that too across the output wires ie AC jack. This 4 volts is from the base magnetism of the rotor. Adding the cap increases the voltage across the "cap coil" this "excites" the rotor coil. The rotor coil thus has DC with the diode thus the magnetism increases in the rotor. The voltage them builds up quickly.

@@3beltwesty Thanks bro 🤙

Its hard to say why. It could be as simple a brush is dirty or wore down to much and lost spring pressure. I would check that first anyway.

Check for correct spec RPM of the welder/generator

If I decide to recoil the rotar how do I figure out how many windings I need

@@musicitt -- just use the old wire to determine the exact measurement for the replacement wire. imo 🤔 it can't exceed a thousand feet 😆

@@Texaca Sounds like an 160 meter Beverage antenna to Me. Yeah

output current would be DC with out the rectifier. Then its no longer a AC generator.

@@MrDoingEverything so technically we can bypass those and make it a strictly DC output generator?

@@off-gridhillbillystyle3735 Well not really because there are other components that work off the AC. So bypassing more then just that would need to be done. I never played around with it to figure out how to but i,m sure its pretty simple. I would guess if only the output leads from the generator were used it would be DC i mean the leads ahead of all the generator components but there would be no volt regulation happening either it would be full output power which could be to high to be able to be used for much. A Regulator would be needed to be used to give a good use able output voltage. I might play around with one beings i have a couple of them that i don.t need as a generator. If i do i will let you know back here on and through this message. If you play around with one let me know. I would play with a carefullness is how i would deal with it. High DC voltage can give a real hard shock.

@@MrDoingEverything I need a low rpm high voltage generator.... Any idea where I could find or scavenge one?

@@off-gridhillbillystyle3735 No other then keep looking.

Yes.

Right the motors are not affected when the power heads stop working. If it was sitting to long sometime the only thing that need to be done is recharge the capacitor and some time also the capacitor will go bad and need changing. Really there is many reasons to why they stop working. There are the most common problems that I would check first. Which one of them is in the video and the other one I mentioned here with the capacitor. Best of luck to ya with it. TC

Residual magnetism is lost. Magnetic field, conductor and relative motion that's how generators produce power

Have you thought about the voltage regulator

@@MrDoingEverything I’ll have to open it up and have a look for it, it’s not like the new generators it’s a Medusa petrol and it’s maybe 30 years old now, 13.5hp engine. I’ll try your suggestion, I’m new to generator repairs, this is my first attempt 😅

@@MrDoingEverything you’re not going to believe this, there isn’t a voltage regulator, or not one that looks modern day. All I see is copper wires, capacitors, or some tiny diodes. What do I do next? I’m so puzzled. It’s nothing like in people’s KZfaq videos

@@belsayshootingground Have you checked the diodes.

@@MrDoingEverything there’s 2 of them on the rotor, they look fine visually, but I don’t know what tests to run?

That.s very hard to do it can be many reasons why. Tests of different things would need to be done to know for sure and maybe a lucky guess will find the issue faster. That's only a luckly guess though and they don't always work out. I have no way to know what could have went wrong. Sorry

Could be the same as in the video.

@@MrDoingEverything it was from the AVR

@@marwans4018 That's it when these type things fail it's never going to mean the same issues for all of them. Best of luck.

Better

Cheap is all fast and cheap and not long lasting.
