Title: Flywheel having a variable diameter for energy storage
Inventor: KUEMMEL PETER DR
IPC: F16F15/31
Filed: 1993-10-12
Abstract: In order to store rotational energy, a flywheel is driven at maximum rotational speed. Tapping energy electrically lowers the rotational speed of the flywheel. In order to counteract this loss of power, the annular inertial mass located on the external rim is divided into at least three segments. In addition, smaller auxiliary inertial masses are arranged in a rotationally centred fashion near the axis of the large flywheel. They also serve the purpose of storing energy, but do not expend it. Their energy is gathered and used in order to draw all the inertial mass segments synchronously and step by step in a radial fashion towards the flywheel axis. The result is an increase in the rotational speed of the flywheel, which can also be held constant much longer.
