Hybrid Car – More Fun with Less Gas

A few idiots in these groups believe Wind Generator must have PMA (permanent magnet) Motor.

Here is why it's bad to use a PMA (permanent magnet) motor for  your Wind
Power:

1) It would require so much strong wind to turn the motor, most of them
output 300watt - 1000watt at voltage not useful to charge your standard
battery.   PMA motors are weak, so many times weaker than NON-PMA motors.
I already tested theirs. So be sure you test their motor with load if
you got one, because they use capacitor to mislead the true output. theirs
is a hyper output!.

2) PMA motor doesn't have any flexibility to adapt to wind power, it's
fixed. Therefore you are a loser if you bought one, its torque cannot be
adjusted  to adapt to wind's power.

3) The PMA makers are usually jalous poeple, they're afraid you will invade
their market, they would try to eliminate your idea if you have something
better.

4) THE PMA-MOTOR USERS/MAKERS called Adjustable Torque motors as junk,
BECAUSE THEY HAVEN'T TRIED IT,   and they don't know anything about it.

-------------------------------------------------------------------------------------------

Why it makes sense to use an Alternator with Automagnet/Autofield
controller?

1) It can adjust itself to any wind speed, any wind power.

2) Generator outputs 4-10 times more power, real power, not hyper power
like PMA motors.

Go away "Richardson"!

Apparently the same "jalous poeple" he spammed (costing him his Ebay
account) forced him to change his name as well!  One would think that
he'd erect a few of those 5kW wonders in his yard and show all the
charlatans what they've been missing.  Heck, put up a dozen of them
and make a living selling the non "hyper output" to the power company.
At least he stopped yakking about the DC advantage of his alternators.
Too funny.

I did a google search and I've found  3,920,000 for "vaugh death"

I got to tell you the truth, your ID reminds me of the death, I swear every
time I see your ID.  You need to have a nicer name unless you came from the
cemetery where your name was given.

It's a bit difficult to take seriously (not to mention read) the
information of someone claiming to be an "Authority" on wind, that
doesn't seem to know the difference between a "motor" which uses
electricity to create motion and an "alternator" (as in permanent
magnet alternator PMA) which uses motion to create electricity.


Sense you've stated that you've "already tested theirs" and I can
presume that you must have tested yours for comparison data, I'd like
to see the test data for BOTH "theirs" (PMA) and your (excited field)
alternators. Please include anemometer data, tower height, rotor size,
number of  blades, along with gearing ratio and field excitement
losses.


This is what your data needs to prove.


Generally businesses just adopt "better" ideas and sell them to their
established markets.


I think a little closer attention to what's been going on in the field
of wind-turbines would helpful here.
 

I hope when you post your data verifying these claims, you'll sort out
the use of the terms motor, alternator, and generator their NOT
interchangeable making there claims very hard to follow.
