Abstract
An energy accumulator has a flywheel journaled in a flywheel housing and is rotationally symmetrical about its axis is driven. The flywheel rotates about its driven axis and when desired is braked. For the defined braking of the flywheel any wobble of the outer periphery of the flywheel relative to the flywheel housing and/or any radial motion of the flywheel relative to the flywheel housing and/or radial stresses/displacements occurring in the bearings are measured as to magnitude and direction and compared with a threshold value. Only when the threshold value is exceeded is the flywheel braked.
