ABSTRACT:
A magnetic levitation motor which rotates a rotor in a levitated state with respect to a stator by a direct-current magnetic field and stator windings. The magnetic levitation motor comprises: a direct-current magnetic field generating device (4) which forms a magnetic flux having a radial pattern with an axis at the center in a stator (2) and a rotor (3); a first stator winding (6) for generating a levitation control magnetic flux (5) to control levitation of the rotor (3) in a radial direction; and a second stator winding (7) for generating a rotating magnetic field to rotate the rotor (3). The rotor (3) is provided with a yoke portion (9) and a motor magnet (10) which are opposed to a stator core (8) of the stator (2). A part of a bias magnetic flux (11) and a part of a levitation control magnetic flux (5) form a magnetic circuit directly reaching the stator core from the yoke, thereby increasing a levitation force of the rotor.
