Re: Toroid Design .



"  Jim -

  This is the first time I have heard that the Van deGraaf motor slows
down
because of the upper electrode voltage. I thought the transfer of
charges
from the belt to the inside of the sphere was because the potential on
the
inside of the sphere was less than on the belt.

	The motor slows down (if it is of marginal power, at least) because, as
the upper terminal voltage increases, more work is being done to move
the charges "up hill". Real effect!
