'Magic Sine waves'

       Me again.
       I have a lead on a possible commercial application of Magic Sine waves a
s
I understand them. Does anyone know where I can get information on them ??
I realize that information of this type is not free.
       Correct me if I'm barking up the wrong tree. A company needs to vary the
speed of some AC motors. Toshiba says that thier controller will not work
in this situation. Long cable run and high voltage. They said the "
Harmonics " would not allow thier controller to work. If I understand Magic
Sine Waves, using them can eliminate most of the harmonics thus allowing
the control of the motors. The company is paying DEARLY for some
controllers now..
       Any info is greatly appreciated.

Have a look at the addenda, by the way I would be interested in how you
progress,
I was looking at magic sinewaves recently and also about 2 years ago. But in
both
cases other jobs came up :(

I think its a great idea but, needs a lot of work, in basic theory and
practice in
implementation etc.

--------------------------- Addenda ----------------------------------

Don Lancaster has written about "magic sinewaves".  Don has a homepage at

http://www.tinaja.com/

Enter the Reference Library, then the Magic Sinewaves Shelf and find this blurb:

                              Don  Lancaster's
                           Magic Sinewave Library

         "Magic sinewaves" are repeating long sequences of ones and
         zeros.  Digital sinewaves with precisely controlled amplitudes
         and amazingly low distortions.

         Compared to traditional PWM, magic sinewaves can offer far
         higher efficiencies and lower distortions. With circuitry that is
         elegantly simple and microcontroller friendly.  For use in such
         applications as induction motor speed controls, electric autos,
         solar panels, power factor correction, inverters, home energy
         efficiency improvers, and specialized utility services.

         There are more magic sinewaves than there are particles in the
         universe. Only recently have specialized analysis tools become
         available. Don Lancaster, Synergetics, and several Synergetics
         Partners are in the forefront of this billion dollar opportunity.

         Extensive seminars, consulting, sourcecode, tutorials, and a new
         Partners program are now being offered.

Hi Mike,
       I read all the data on the Magic Sine Waves that I could find on his
site.. still confused. I understand the idea. Make your own sine waves
based upon digital signals that are not regular so you eliminate harmonics.
Is there some sort of formula available ?? Is that something that I would
have to pay for ?? I'll send Don some email and see just where he stands
and what is available.
       Thanks for the reply to my post.

Yes - his formula is written in postscript language.

Good luck - I tried about 3 times over last 6 months...

Some say there is no magic but, all things begin with thought then it becomes
academic, then some poor slob works out a practical way to implement all that
theory, this is called Engineering - for most people another form of magic.

i recall someone asking about magic sine waves, and ran accross
an article in June 1995, Circuit Cellar. check it out.
