Hi.  I'm interested in finding out as much as I can about hysteresis motors.
I've exhausted my local library books, and am now looking for papers.  If 
anyone out there has any knowledge of these devices, please speak out.  I'm
particularly interested in two points:

   1.  Large hysteresis motors.  The biggest one I've seen reference to is
       in the 30-40 hp range.

   2.  "Speed flutter".  Veinott and Martin indicate that these motors may
       produce a "flutter", which they define as a variation in speed during
       rotation.  It's important that I learn if this can be avoided, and if
       so how.

Thanks for any help you can give!  Sorry, I have no signature yet.
