Abstract
An electric motor having a rotor and stator includes a magnetic hollow rotating shaft to which the rotor is fixed. A magnetic cylindrical bearing is inserted into the magnetic hollow rotating shaft such that a radial repulsive force is generated between the magnetic hollow rotating shaft and the magnetic bearing. A first fixed magnetic member is disposed at a top of the magnetic cylindrical bearing, and a rotating magnetic member is disposed at a top of the magnetic hollow rotating shaft such that the magnetic hollow rotating shaft can be supported by axial repulsive force generated between those magnetic members. The magnetic members are vertically adjustable for varying the axial clearance therebetween.
