The motor is arguably the least critical aspect of the Van de Graaff generator. Obviously, you want one with enough horsepower to drive the belt. Try looking at local motor repair shops. I even used a circular-saw motor at one point. For the motor speed, I would not use anything less than 1,000 rpm. Read formulas, definitions, laws from Van de Graaff Generator here.

Van de graaff diagram

A person insulated from the ground and touching the dome of the Van de Graaff generator will also lose electrons and become positively charged. The same will happen to each of their hairs. Since the person, their head and each of their hair follicles are all positively charged, the hairs will ... Van de Graaff experiments are all based on the fact that like charges repel. A Van de Graaff generator pulls electrons from the Earth, moves them along a belt and stores them on the large sphere. These electrons repel each other and try to get as far away from each other as possible, spreading out on the surface of the sphere. Your Van de Graaff generator arrives in three pieces: 1) the fully assembled main unit, 2) the top half of the dome, and 3) the discharge wand. Carefully unpack all three pieces from the shipping carton. Set the main unit on a sturdy wood or plastic (not metal) table. Fit the top half of
