Help finding out what a component is.
« on: November 07, 2024, 07:50:51 pm »
Hello, newbie here :)

I recently got an old sewing machine called Norsy Type 4 (which i think is just a rebranding of an Anker Phoenix Gloria Automatic).
And it runs! which is great!, but when i opened it up to clean it, i saw that the first component the power goes in to, looked broken.

Might not be anything dangerous, but i don't feel super safe having 240 volts enter a thing like that.

I have added pictures of the broken par and a text of what i think it says on it.
I have as well added a picture of the engine.

To me it looks like the broken part might be multiple parts? as the first line is a capasitor, and the second line is a fuse, but thats just guesswork through googling. any ideas of what it might be and how i could go about replacing it?

PS: i dont mind soldering as long as i know what goes where.

Thanks a bunch in advance

That's a mains EMI (interference) filter and specifically, one of its capacitors has 'let go'.

Since the metalised film of the capacitor is now exposed, and maybe at mains potential, I'd be inclined to either remove it completely (using a suitable mains cable joiner to join either the mains input to the power switch, or the motor to the power switch directly, depending on where in that chain the filter already is),  or replace it with a suitably rated new unit.

It's probably just a line filter to prevent EMI from the motor from interfering with the radio/TV.
Modern versions come in various forms:

Yes, it's a filter.
The second line is not for a fuse, but it's the nominal max current rating for the filter.
But I am a bit surprised I don't see any inductors in there.
