PROTOTYPE
'NIRVANA' ALTERNATOR
Information about the biggest axial flux alternator
I have built -
updated December 2009
The actual wind turbine (Alan's) has been in action since about
1998.
You can see pictures of it near the bottom of my year 2000 tour page.
BLADE DIAMETER 5 metres / 16 feet
POWER 4000 watts at 220 rpm
Page 1 shows the first alternator we
made, using 46 x 30 mm magnets MAY/JUNE
2004
see page 2 for
erection and subsequent events...
It wasn't really up
to the job, so we built another one using longer 70
mm magnets.
So
far that has
worked well and we are building more with this magnet size but using
more turns per coil.
Now we use 80 turns of 1.6mm wire (14 AWG)
in the
coils.
