can make 1,400 volts if you spin it at 18,000 RPM or it can make
12 volts if you spin it at 200 RPM. The '120' code is ONLY a

MORE STRAIGHT TALK FROM OUR CUSTOMERS:
A great way to show how much better
your rotor designs are vs the
competition with one mag and the Chinese
wind gens with wound rotors.
Ive been studying converting a wound rotor to a pm rotor. But
your design of multi mags on the outside put 4 to 6 times more
There is only so much field you can get in an iron core. about
Now a wire wound core has to divide this between the usual 6
the rotor for 1/6 of the possible mag field at each pole/coil.
But a typical #42 NDB has 13G so each coil gets 13G not 16G/6
So the multi mag core is 13/2.66 (4.88) times more powerful than
electro rotor and 6 to 12 times more powerful than a pma with
and NDB magnet ring because half the field goes on the inside
rotor and the rest is divided into 6 poles.
Might be a good selling point over the other pmas that use a
in an old core.
Note the larger axial pma's will put out a higher voltage at
because the magnets are moving faster across the coils at the
The bigger the rotor the higher the voltage per rpm.
