This is the motor for the electric generator
I will fix it for a guy who works for a pharmaceutical company in my hometown
I have done it once but it didn't work, so I decided to continue to fix it
It is not clear which country it is from, because it is a fake
There is a DC motor inside
It has a gear system to transfer power
The motor runs very fast, but it runs slowly
When it is cranked, it presses down
It has a cover to keep it in place
I don't know which country it is from, maybe China
There are 2 buttons on the motor, when you press it, it rotates
When you press it, it rotates backwards, and when you release it, it doesn't run
There are 4 moffets that form a H-shape
There are 2 moffets for the N-channel and 2 for the P-channel
They form a H-shape to convert the power of the battery
This is the diaphragm and this is the note, the motor rotates backwards
This is the diaphragm and this is the note, when you turn it upside down, it rotates
These 2 moffets are for charging
When I tried it, there was a 5V charger
When I tried it, there was no warning light
And it didn't work
I checked and found an IC
TC4056A
I was going to buy it, but I found it in the charger I bought in China
It has an IC for charging
This is it
It looks like the real thing
It's a battery charger
There's a light here to charge
I think it's a faulty battery charger
No, it's not
I think it's a faulty battery charger
But I think the Vietnamese products are much more expensive than the Chinese ones
But it's not all, it also comes with this thing
It's also amazing
You can refer to it
This is the battery
This is the one in the middle of the box
It's a LAN port
We will split the LAN for each way
But we will look at this thing
It's very solid
The network is very strong
Guys
It's great for those words
I don't know which country it's made in, but it has the word chi-la here
A specialized chi-lan set from the repair companies
It's broken, some diodes are broken
It just fits a few, but this one is missing
Book diodes
Now I'm going to take this one out
This one is slipped
Let's try the DC one
If you want to take it out, you have to pull this one out
There is another DC below, but I don't know what kind of DC it is
I will pull it out
Here I have a power supply, for example, I am using a power supply, I will connect a power supply
2 volts, 3 volts
I will connect
reverse
It runs like this, and the other way around, the H bridge with 4 plugs will be reversed
That's it
And it has a good thing, it has a good thing to buy this circuit to press it
It has a small DC, I don't know what it is, now I will try to replace it
Put it here to replace it
To avoid burning the bottom
The power supply is not broken, I have tested the power supply
This DC does not change, it does not change the operating mode
This is a logic IC
I used to call it IC number
These are the logic ports
NAND port
OR port, OR port, etc.
I have tested it in NACHA
Now I'm going to take this one out and put it on
Can't turn it
Keep it
This one has glue underneath, it's terrible
It's not glue, it has a back
Oh, it has a back
Can this be replaced?
It has heat dissipation
It is very difficult to remove
The other one does not have heat dissipation
Does the heat dissipation touch the bottom of the machine?
Remove it all
In the afternoon, it has a leak
The foot is not working
The foot is stuck in the cabinet
Try it
Will it turn on the light?
It turns on the light
This one is dead, but now I will try to see if it will turn on the battery
It turns on the light
Let's see if it can charge the battery
This is the map
This is the diameter
It is 4V to the battery
I am charging
It is 4V to the phone charger
Try it
Will it turn on the battery?
I don't know if it will turn on the battery
It turns on the red light
Nothing
Let's try this way
I don't know what kind of IC it has
Let's try it
I don't know what are those 2 screws for
It has 4 screws
I thought it was a magnet, but it's not
It's a magnet
Let's try it
This is the 4V power supply from the power supply
Let's try it
If it doesn't work, I'll have to think about it
Put it in here
Put it in the middle
That's it
It doesn't work
It's not working
Nothing
Let's check it out
I don't know what these 2 screws are for
It works
I don't know what it is for
It works
It's like a battery protection system
I'll put it like this
It will turn on the battery
Let's try it
It's not working
It doesn't turn on the battery
Let's see
It's working
It's 3.8V
Let's put it in
It doesn't work
It doesn't turn on the battery
It's working
It's like a battery protection system
It's not working
Let's try another one
It's not working
Let's replace this one
It's a small one, you guys can't see it
It's a small one, it's a battery protector
It looks like a replacement
Let's see if it's the right name
DVF01A
It's exactly the same
But this one is a little too big
Let's see if we can replace it
It's so funny
Maybe this one is made by a Chinese man
It's a battery charger
It's also a battery protector
That's why it's a Chinese brand
We have to know the right way to remove it
There's a problem with the wrong way
It has to be like this
Otherwise, it will cover the battery
It's too much, I have to pull it all out
It has to be like this
It's stuck
It's stuck together
Let's see if it works
I think we have to plug it in and charge it
It works
It's great
It's so cool
It's so funny
Let's see if it works
It's charging
Let's plug it in
It's charging
