Hi guys
I need some help about electricity, I thing my grandma knows more than me about it
We have built a machine with 18 coils-24 mags (dual rotor)
It's a vawt
The coils from 22 awg wire & mags 2X1X0,5 neos
We connected the coils for 3 phase star the way you see (is it ok?)
(Link removed until someone smarter than me looks at it)
Now, we found
On 60 rpm 58 volts between start & end of one phase
On 120 rpm 80 volts
On 150 rpm 100 volts
On 60 rpm 80 volts between two phases
On 120 rpm 150 volts
On 150 rpm 180 volts
And
On 60 rpm 55 volts between a phase and neutral
On 120 rpm 80 volts
On 130 rpm 150 volts
We try to measure the amps but we cant.
We suppose we can find the amps from this : V=I*R, so I=V/R
From the AWG table for copper wire we see that the resistance (R) for the 22 awg wire is 53 ohms/km.
Now,
For each coil we have about 38 m copper, means for 6 coils (one phase) we have
38*6=228m copper wire, means about 450m for 12 coils (when we connect and measure between 2 phases.
I suppose it gives about 24 ohms, so the amps must be 80/24=3,3 (60 rpm-80volts)
And 150/24=6,25 (120 rpm-150volts).
But we don't have so many amps really.
May be simply (or silly in fact) calculations.
Is there another way to find the amps?
What is the power we can get from on these rpms-volts? (60-80, 120-150, 150-180).
Gently please, we are mechanics not electricians
Thanx
