Dia. Mag. Alternator

[z.monkey]

Can you measure the shaft diameter, and the rotor diameter?  If I have those dimensions I can probably pick parts out of a catalog that would drop in.  Then all you have to do is replace the parts and spin the shaft.  That is a lot easier than what I have done here...

I love salvage parts...

Edit:  That rotor may already be a neo dia mag, so it may not even need replacing...

Look, the gears got a face lift...

Thin is sexy...

Uh, I have to take, uh, her, apart again...

I hope you don't mind...

I did another electrical test this morning...

Open circuit voltage is 17.34 Volts.

Loaded with the 65 ohm resistor it drops to 5.84 Volts.

Which gives a current of 90 milliAmps.

And that is about half a Watt...

The gears work great, they are the least of my worries...

The poor electrical performance is because of the wire I chose.  I measured the resistance of the coils, 25 ohms !?!?  No wonder there is no current.  This is probably the most fundamental thing I screwed up trying to be cheap.  I have this old spool of 22 AWG magnet wire, and figured its no cost, gotta use it.  I'll go for high voltage.  Not thinking that the big resistance would turn my alternator into a fancy, spinning choke.  So, you can guess what's next.  Rewind...

Gotta take it all the way apart again...

This time I'm thinking about using 16 AWG magnet wire...

Edit: Forgot to mention that I weighed it this morning, 8 1/3 pounds...
