The invention discloses a method for making a rotary plate continuous rotation electrostatic power machine. The power machine mainly comprises an electrode plate, a rotary plate and a high-voltage electrostatic power supply, and is characterized in that the electrode plate comprises a plurality of even N metal conducting flat plates; the rotary plate comprises a plurality of positive integer M metal conducting flat plates with smooth surfaces and the same material and size; the positive integer M is a number M less than a number N and is a common divisor unequal to 1 and N; the electrode plate and the rotary plate are cut into the structure with the same comb shape; the width between the comb part of the electrode plate and the combs of the rotary plate is less than a gap width among the combs; the rotary plate can freely pass through the electrode plate during rotation; when the rotary plate is rotated to pass through the electrode plate, the top of the comb is just in contact with the bottom of the gap among the combs. The experimental design contributes to promoting cultivation of initiative spirit and practical ability of students. The method is extremely simple in manufacture and obvious in effects, is capable of increasing educational functions during teaching and is a significant operation with developed prospects.
