Abstract:
A magnetically levitated motor comprising:at least one stator having a winding group for rotation and a winding group for levitation, each of the winding group for rotation and the winding group for levitation having concentrated windings spaced at intervals of 30 degrees in a rotational direction to provide induction conductive winding sections at twelve locations; and at least one rotor having a rotor magnet magnetized to have four magnetic poles arranged adjacent to one another in a rotational direction at intervals of 90 degrees, the stator and the rotor being confronted to each other while the rotor is levitated in a direction orthogonal to an axis of the rotor and rotationally driven by magnetic force, wherein each two of the induction conductive winding sections spaced at an interval of 90 degrees among the twelve induction conductive winding sections are functionally connected to form a winding set such that six winding sets are formed in total in each of the winding group for rotation and the winding group for levitation.
