Description

  The present invention relates to a magnetically levitated rotating mechanism (motor, gear) that can be mounted on a vehicle.

The superconducting flywheel currently being developed places the entire device in a vacuum. The flywheel is a top type. For this reason, rotation axis shake is likely to occur due to Euler's equation of motion. Further, the conventional apparatus has a problem that it is large and complicated in structure.
Also, with the vertical rotating body supported at the stable rotational position by the control type radial magnetic bearing and the control type axial magnetic bearing, the superconductor is cooled and the superconducting bearing is activated, and the superconducting bearing and the radial magnetic bearing are used. There has been proposed a superconducting bearing device that stably supports a rotating body and starts operation by rotating the rotating body (see Patent Document 1 below).

However, the conventional apparatus has a problem that the structure is large and complicated, and the cost increases.
