Rotary friction generator capable of outputting constant current

Abstract

The invention discloses a rotary friction generator capable of outputting constant current, which comprises at least one first sub friction piece and at least one second friction piece, wherein the surfaces of the first sub friction piece and the second sub friction piece are provided with a first sub electrode and a second sub electrode respectively; the tail ends of the first sub friction piece and the second sub friction piece are provided with a first conductive component and a second conductive component respectively; the other surface of the first sub friction piece can carry out friction sliding with a constant speed in a clockwise or anti-clockwise direction relative to the other surface of the second sub friction piece. The rotary friction generator enables the two friction pieces to always keep contact friction through constant-speed circumferential motion, thereby generating inductive charge, driving flow of electrons in an external circuit, and realizing output of constant current through using the conductive component as a commutator. The rotary friction generator is simple in structure, convenient to realize and low in cost, can be used for providing power for an electronic device continuously and stably, and can also be used for providing power for a capacitor continuously and stably, and has very good social and economic benefits.
