  • Patent number: 9206788
    Abstract: [Problem] To provide a electrical generator capable of obtaining a more stable power generation by preventing a spindle body from tilting and swinging to the right and left due to centrifugal force acting on the spindle body. [Solution] A electrical generator (1) has: a rotating body (2) that rotates in a vertical plane about a rotating shaft (21) supported substantially horizontally; a rotation drive means (3) for rotating the rotating body (2); a plurality of power generation motors (4) disposed at equal intervals on the same circular orbit centered on the rotating shaft (21) of the rotating body (2); and a spindle body (5) hung at the motor rotating shaft (42) of each of the power generation motors (4). The spindle body (5) weighs such that when the rotating body (2) is rotated at a predetermined rotational speed, the gravity thereof is larger than the centrifugal force acting on the spindle body (5), and the center of gravity thereof is set close to the motor rotating shaft (42).
