Alright, trying to replace this copper off this rod with some permanent magnets to make a little windmill. I'm just wondering the best way to go about it, and to glue the magnets back on the rod. More pics to come.

youre not going to make very much power out of that

if you still want to do it, leave the copper on the rotor and drill divots in the core (where the slashes were done for balancing). put your magnets in the divots and epoxy them in place.

or how not to make an electric generator, by OP.

Alright sounds awesome. But, what would be a better diy generator? Am I better off building my own from scratch, copper and all? Or getting something bigger, like an alternator?

>>1119604
Sorry for my ameture approach. This is my first time trying this kinda thing and I needed to start somewhere.

Judging by the commutator i would guess thats a DC motor. If you still have the brushes intact (they have wires connected to them and would touch the end of the armature on the opposite side of the coil from the fan) i would just replace the stator windings instead of tearing apart the armature and glueing magnets on it. It would be a lot less fucking around.

just get an alternator from a junk yard

Came to post this.

Do this >>1119603 first since it will be a very quick install and you can play around.

If you want to make something more powerful, you will need to buy some enameled magnet wire to make your own coils and pair them with some N52 magnets. The easiest way to do this is to attach them to something that already has a spinning parts and some nice space to mount everything to. Like a junk ceiling fan motor. Those have nice flat spaces.

If you don't want to make your own generator in that manner, just use any DC permanent magnet motor and crank it with something. Those can be sourced from lots of easy places. Some AC motors will work easily if you slap a bridge rectifier on them.

How much energy are you wanting to create? That is where to start.
