Abstract: A power generator includes a heavy gyro body, a driving device, a transmission disk and an electricity generation module. The driving device is used to drive the heavy gyro body to rotate about a vertical spindle. The transmission disk is secured to and rotatable simultaneously with the heavy gyro body. The transmission disk has a plurality of rollers at a sidewall thereof. The electricity generation module has a rotation disk, which has a plurality of inclined grooves at a sidewall thereof. Each inclined groove is meshed with a corresponding roller of the transmission disk such that the transmission disk is able to drive the rotation disk to rotate, wherein an included angle between an inner sidewall of each inclined groove and a horizontal plane is more than 0 degree and less than 45 degrees.

Abstract: A power generator device includes a heavy gyro body, at least one rotation-driving device and a control unit. The heavy gyro body is coupled to a power source and an induction power generator, the power source drives the heavy gyro body to rotate so as to drive the induction power generator to produce electricity. The rotation-driving device is located at an edge of the heavy gyro body and conducting a contact or non-contact interaction with an annular part in reaction to drive the heavy gyro body to rotate about a vertical spindle. The control unit is configured for starting the rotation-driving device to accelerate the speed of the heavy gyro body when a rotation speed of the heavy gyro body is less than a first predetermined rotation speed.
