Coil Wiring

Hey all, I got the coils wound,the [in] lead and the [out] lead....all the same for each coil. Now, does all the [in's] tie together and all the [out's]...Or is it,a [in] to the [out].Oh,And please don't tell me, series or parallelllll.[grin]..I just need to know where the wires go.
I did build a 6 ft. blade,,it turns nothing yet, but the wind turns it just fine and fast. Pearl

The type of connection depends on whether you want to maximize the voltage or the current. The example shown is a 4-pole winding, but the principles can be applied to a winding with any number of poles.

Thank You Ed, Are there only two main wires that connect these coils and comes down from the tower? and what is the better to have? voltage? or current? And Is current Amps? Or
maybe both,and thats why its wired both ways? I'm tryin to learn.Thanks for your help Ed

"Are there only two main wires that connect these coils and comes down from the tower?"

Yes, if it is a single phase machine. Could be three, or even four, wires if it was a three phase machine.

"And Is current Amps?"

Yes, current is measured in amps.

"and what is the better to have? voltage? or current?"

It is the current flowing through a load device, such as a lightbulb, heater, or motor that makes it operate, but voltage is required to force current through the resistance of the device. So both are required for the device to do "work".
The rate at which work is done is measured in watts, and watts(W) are calculated by multiplying volts(E) times amps(I). W = E x I

"Or maybe both,and thats why its wired both ways?"

The option to connect the coils in series, parallel, or series-parallel, helps adjust the machines output to match the requirements of the load.

For battery charging, which is the most common application for wind generators, the charging current must be forced through the battery "backwards", so you need sufficient voltage to overcome the battery voltage, plus the internal resistance of the battery.

Hi,

in order we can know
that you are doing it the right way,
you need to tell us,
how your alternator is made.

---------------------------
If you made it like 'The Volvo Alternator'
of the otherpower.com
with laminates,
then your magnets
are not all the same way but
... ,N,S,N,S, ... ?
----------------------------

In that case to put your coils in series
to get maximum voltage
you have to hook your coils:
- in - in - out- out -

The easiest way to get it right
is to connect the coils one by one
and by turning the alternator by hand
and measuring with a volt meter
to make it sure
that every time you add a coil the voltage rises.

In principle if you put all the coils in 'series'
you get the maximum voltage at the lowest RPM.

In some cases if you made your coils
with really many turns you don't need to put
them all in 'series', but can use the same
wiring as the original 'Volvo' alternator
so that two halves are in series
and those halves are then wired 'parallel'.
