Abstract

A magnetic levitation propulsion system for magneti levitation train is disclosed. Its advantages are self-adaptive and self-stabilized levitation force, great magnetic levitation gap, and high safety.

Description

Technical field: [0001] The invention relates to the technical field of electromagnetic power, in particular to a magnetic levitation propulsion device. Background technique: [0002] Existing maglev trains are divided into two categories: normal conduction and superconduction. The constant conduction type is also called the constant conduction magnetic suction type. It is represented by the German high-speed constant conduction maglev train transrapid. It uses the principle of electromagnetic attraction of ordinary DC electromagnets to suspend the train. The suspended air gap is small, generally about 10 mm. The speed of the conventional high-speed maglev train can reach 400-500 kilometers per hour, which is suitable for long-distance rapid transportation between cities. The superconducting magnetic levitation train is also called superconducting magnetic repulsion type, represented by MAGLEV in Japan, which uses the strong magnetic field generated by superconducting magne...
