<p>Improved flywheel comprising a disc (2), housed at the end of a shaft (3), with a plurality of sectors (4) arranged on a plane, with axis passing through the centre of rotation (5) of the disc (2) of equal base area, characterized in that said sectors (4) have a mass difference equal to at least a sample mass unit, defined as the minimum mass difference of two sectors (4) of the disc (2) as well as the greatest common denominator between the masses of the same sectors (4). In addition said disc (2) comprises a couple of opposite sectors (4), arranged on a plane with axis passing through the centre of rotation (5) of the disc (2) with a mass difference equal to a multiple of sample unit greater than one.</p> |
