Our PE department got rid of a bunch of exercise equipment. I pulled a
nice commercial exercise bike out of the metal recycle and had the kids
strip all the plastic off of it, and I found the guts of it are an
automotive type alternator and a big resistor. I want to hook it up as
a current source for a battery charger/light bulbs/ammeter/something to
give the kids an idea of how much actual work a KW is.
The alternator is a Mando 38611-101. A picture of the alternator is here:
http://www.gympart.com/itemdesc.aspx?ic=LCA10
If you look at the picture on the link above and rotate it 90 degrees so
the black plastic part is at 6:00, it has the following terminals:
On the black plastic part, "Ex" and "S".
On the main body of the alternator, clockwise from 8:00 the terminals
are "L2", "P", "B" and "E". There is also a ground terminal.
If you look a this chart,
> http://dasko.co.nz/articles/alternator-terminals-explained
It looks like all I would need to hook up to would be the "B" terminal
and the ground and I can ignore the rest.
Do I have this right?
On an automotive alternator how fast does it normally have to spin to
put out 12V?
Thanks
Dave
