What is in the electrical system of a hand mixer?
Hello everyone,
While I was chopping candied orange peel with my hand mixer for a while, the inside of the mixer suddenly lit up and began to smell horribly. It also started emitting smoke. It then stopped working.
I opened it and looked inside. Suspecting the capacitor was the source of the problem, I removed it with a soldering iron. Now the inside looks like the photos.
I would be interested to know the names of the parts numbered in the photo and what their function is.
And I'd be interested to know why the capacitor breaks when you "overuse" the device.

Did he have any optical damage? A defective capacitor can be seen when the one has sparked and quarried. You haven’t photographed it…
It doesn’t break when the device is overloaded. A motor damage is much more likely. This is most loaded and overheated by the engine… The coals and the collector don’t like that.
I’ve got pictures from the condenser, it looks totally inconspicuous. But I couldn’t find any damage to the commutator and the coals.
So the capacitor certainly didn’t radio and qualify….
You don’t see that directly at the commutator either. Carbons become somewhat narrow due to the heat, and this is between the grooves of the commutator, winding closures and insulation faults occur between the individual plates and thus creep currents, light burn off, the coal surfaces are no longer neat. This results in spark formation and smoke development… In the same way, my old cordless screwdriver died… Immediately nothing to see as soon as you have let him run, he has qualified, you could see the light tracks of the faulty connections, arc formations on the coal surfaces to the commutator… That’s shredded.. It is worth noting and cleaning/grinding as well as coal exchange.
1 is a fuse
2 and 3 are resistors
4 shows a diode
5 most likely a bridge rectifier
the burned capacitor is presumably designed as a dedusting capacitor and possibly from to phase correction. You can’t just build it out, but you should replace it with an equivalent one.
On devices with mains voltage you shouldn’t sit around without a corresponding qualification! Apart from the fact that this can be life-threatening, it is also illegal.
This looks like a very inexpensive device anyway. Think about a new one!
Measure the engine to resistance. I can’t imagine the capacitor as a reason for the fault in the best will. It also hangs parallel to the entrance. That’s why he wouldn’t make any problems when he burned down. In addition, capacitors blow up at most or burst.
Theoretically, the diode D1 or the bridge rectifier C1 is also conceivable. You’d definitely look at the resistances.
