Microwave oven fan rotor

[Paul-R]

Hi.
I just took apart an old microwave oven

There are two nice ring ferrite magnets in the magnetron assembly.

Also, the main 8:1 transformer is worth your attention. I cut through the
laminations with an angle grinder (do the last it with a hacksaw), and
soaked it all in water overnight. This softens the paper padding, and the
two coils can, with difficulty, be eased off. An inexhaustible supply of
fine enamelled copper wire.

Don't forget your capacitors (with a 1megohm resistor connected internally,
unfortunately), some handsome power diodes, and a diddy motor which will
keep your jeans rotating on your washing line to speed up drying.

Damn !

I took all of that apart from the diodes, they looked like wire-wound resistors to me

That'll teach me !

Paul-R, Yes - garage sale microwave ovens (got several) are an energy builders delight     I hadn't thought about cutting up the transformers - good idea!

Deepcut,  the magnet I wanted was going to cost something like $20 with shipping - the shipping was more than one magnet but IIRC I could get about 4 or 5 of them for around $30.  So I'm penny pinching at the moment and waiting to find a better deal somewhere.
