Abstract:
A magnetic levitation motor comprising:a rotator body formed from a magnetic common rotation member and having segmented permanent magnets attached to a peripheral surface thereof, wherein surfaces of the segmented permanent magnets face a stator; and two magnetic levitation motor sections disposed in an axial direction of the rotator body, each of the magnetic levitation motor sections having a first stator winding that generates a levitation control magnetic flux for levitating the rotator body and a second stator winding that generates a rotation magnetic flux for rotating the rotator body; wherein the segmented permanent magnets are affixed to the rotator body at the two magnetic levitation motor sections; wherein surfaces of the segmented permanent magnets affixed to the rotator body that face the stator at a first of the two magnetic levitation motor sections have exclusively a first magnetic polarity; and wherein surfaces of the segmented permanent magnets affixed to the rotator body that face the stator at a second of the two magnetic levitation motor sections have exclusively a second magnetic polarity opposite that of the first magnetic polarity.
