Done. However, this switching may be controlled depending on the amount of power generation. As a result, the magnetic bearing is not operated during low-speed rotation, so that there is no wasteful power consumption.

When the rotating body 1 magnetically levitates, the resistance for supporting the rotating body 1 decreases. Even if the wind power subsequently weakens, the rotating body 1 is magnetically levitated in a non-contact manner, so that the power generation amount is maintained for a while due to inertial force and the like. Therefore, unlike the conventional case, the strength of the wind does not directly affect the power generation amount.

Furthermore, since the magnetic levitation occurs at high speed rotation, there is no mechanical contact, the life is long, and periodic inspection is unnecessary. Also, fluctuations in electric power due to the strength of wind power or the like can be suppressed to a considerable extent.
