Abstract
A micro power generator is provided, including a cam structure, an electromagnetic unit, a first clutch, and a first energy converting unit. The electromagnetic unit is partially disposed in the cam structure, which includes a central shaft and a first shaft gear. The first shaft gear is rotated with the central shaft. The first clutch is telescoped on the central shaft, and rotated with the first shaft gear. The first energy converting unit is connected to the first shaft gear of the electromagnetic unit. In an energy-storing state, the first clutch is connected to the cam structure and is moved with the cam structure and the first shaft gear to move the first energy converting unit and to store the kinetic energy of the cam structure to the first energy converting unit. In a power-generating state, the first clutch is separated from the cam structure.
