いて、重要なことである。In such a flywheel device, the inside of the large diameter container (4) that houses the power of the flywheel device is normally used in a vacuum state to reduce windage damage caused by the rotation of the flywheel C11). It is. Furthermore, it is not easy to create a vacuum inside the small-diameter container (8) that houses the generator motor (5) due to problems such as temperature rise due to heat generated by the generator motor (5).
This becomes possible by separately considering the law of order (6). In this way, creating a vacuum inside both containers (8) and (4) reduces windage loss due to rotation and increases the efficiency of using stored energy, and in the flywheel device, It's important.
