PROBLEM TO BE SOLVED: To provide a magnetic levitation device capable of supplying a large power to a levitated body, and not requiring a stable levitation control mechanism of the levitated body.SOLUTION: A primary coil 12 of an electromagnet 10 on the stationary side and a second coil 22 of an electromagnet of a levitated body 20 are coupled by magnetic field covalent bond, and power is supplied efficiently from the primary to the secondary in non-contact. Input frequency of the electromagnet 10 on the stationary side is set in the vicinity of the resonance frequency f1(<f0) of magnetic field resonant coupling, and the attraction force balancing the gravity of the levitated body 20 is set in such a range that the attraction force increases as the gap between the levitated body 20 and the stationary side 10 increases, and the attraction force decreases when the gap decreases. The magnetic levitation device has self-equilibrium, and does not require a control mechanism for levitating the levitated body 20 stably. |
