摘要：
In this study, we propose a new magnetic levitation synchronous motor with a high-Tc superconducting bearing. The levitation rotor obtains the levitation force by the magnetic attraction and the restoring force (axially and radially to the shaft) from a superconducting bearing. The levitation rotor to which the magnetic flux concentration method is applied has a large magnetic field outside of the rotor. Because the superconducting bearing constrains this concentrated magnetic flux, the rotor obtains a large restoring force. In addition, a superconducting bearing with a small bulk can be realized. We stabilized the rotor using this method and confirmed that this motor passed the resonance and that its speed increased to approximately 3500 [rpm] without control.
