Title: METHOD AND DEVICE FOR STORING ENERGY IN A CENTRIFUGAL MASS
Abstract:
The invention relates to a flywheel with four moving mass parts (1). Said mass parts move under the effect of the centrifugal force between a position at a minimum distance and a position at a maximum distance from the rotational axis (2), so that the mass inertia of the centrifugal mass also varies between a minimum and maximum value. In the case of known centrifugal masses, such as the axially displaceable revolving disk flywheel (5), the mass inertia is constant and determines the size of the necessary driving torque. The inventive flywheel only has to overcome a reduced mass inertia during starting or increasing speed which has previously decreased, so that a reduced driving torque is required. This results in a greater storage capacity at a given driving torque. The method and the flywheel can be applied especially to electric drives, especially with a battery or solar generator.
