LeviGyr
Anotace
The golden coin with the logo of the Czech Academy of Sciences floating in the air demonstrates the principle of temporarily storing electrical energy into the energy of rotational motion of a flywheel. In this case, the flywheel takes the form of a coin. To prevent the rotation of the flywheel from stopping due to mechanical friction, which occurs in common sliding or ball bearings, the flywheel (coin) is mounted on a magnetic suspension and utilizes several magnets and an electromagnet.
