New Chinese Power Generator: Voltage Regulator Breaks & Replacement - Causes & Solutions

Question

I warmly welcome.

In my new Chinese aggregate the voltage regulator has broken (I thought so),
so I ordered a new one (cost PLN 48).
After connecting the new one, it worked for about 10 seconds (voltage on the voltmeter about 230 V.).
And my question: was this new regulator defective or is the winding damaged and it damages the voltage regulator.
I will also write that no receiver was connected to the device after replacing the regulator.

Write something more, what about an aggregate? What winding (aluminum or copper)? What power rating? Does it have stable turnover?

It is worth to attach photos of winding leads together with measurement of their resistance

Check what voltage the voltage regulator is supplied with (constant or variable and size). During the connection of the regulator, did you mistake the cables (plus and minus), which could also have an impact on the damage.

Hi.
For sure I didn't make any mistakes, as for power supply, I thought that these regulators are universal.
After below I put some photos of this aggregate.
As for the questions @ soniak2, the resistance on all 4 outputs (these 4 shafts) is 0 ohm

.

soniak2 · Answer

0 ohm between each connector on the cube? It would be best if you wrote all the combinations on the photo

I'm sorry I haven't written back for so long - no time.
I have a question. Maybe I used a module with too low power?
4.2 kW is written on the aggregate housing, and the module supports from 2 to 4 KW.
I would like a link, which module to buy.

If you still have trouble with this aggregate, in particular with the regulator (for the condition of the windings you guarantee), then disconnect the regulator. Instead of a regulator, connect a smaller 12 V battery (e.g. scooter), observing polarity and start the generator. If the aggregate (except for the regulator) is operational, it should work and generate voltage of approx. 150 V, due to too low power supply to the rotor. Performing such a test (observing the safety rules), you will make sure whether the generator is junk or just a regulator.
You were supposed to check and provide the result of the measurement of the voltage supplying the regulator, in particular whether it was powered by direct or alternating voltage, which could have affected the regulator damage.

Hi.
I'm sorry that it takes so long. Recently, the seller sent me a new regulator, but after connecting it to the aggregate, the output voltage is lacking.
So I connected the charger to the generator and the output appeared voltage of about 120 V.
So I guess it's the regulator's fault and I'm probably unlucky and the seller sends me damaged regulators.

I'm sorry that I write a post under the post, but the repair of my aggregate is a bit delayed. I will add a photo of the voltage regulator. I hope someone will tell me which regulator I should order.

If it wasn't for this resin, yours could be repaired.

makada · Answer

Will you advise my friend what regulator should be bought?

wmazek · Answer

Hello !
I suggest checking the generator carefully. You must also have voltage supplying the regulator / about 90 V idling speed / and voltage at the measuring tap / 16-18 V /. The main winding is important but also the rotor winding is important.
Good luck.

makada · Answer

Hi.
Please write on which pins of the regulator these voltages should appear.
Today I have connected the rectifier again and the output has 220V.
When I touched the regulator's negative wire in place of the negative connection of the brushes, there was a spark on the contact, so the power supply to the regulator seems to be.

wmazek · Answer

Welcome back!
The regulator is usually powered by yellow wires and there should be about 90 V, and the other two wires are a measuring tap - voltage control and there should be 16-18 V. Check all connections carefully.
Good luck.

makada · Answer

This 90 V should be between wires or to ground. Because it is by all means and I get around 6 V. but if I attach the regulator, it connects to the brushes, and so the current goes to the brushes.
