Abstract

The invention discloses a super-conduction magnetic suspension linear electromagnetic propelling system, relates to the field of a motor, and aims to solve the problems as follows: the magnetic fieldformed by a super-conduction magnet of the existing magnetic suspension propelling system is open on a vehicle, which causes severe magnetic leakage and high magnetic field shielding difficulty; the vehicle is high in weight and the conventional conduction magnetic suspension technology is relatively low in suspension height, which causes high suspension control difficulty, and relatively high requirements on circuit flatness, roadbed sinkage and turnout junction structure. The invention provides the super-conduction magnetic suspension linear electromagnetic propelling system; and by adoptionintegrated suspension, guiding winding and series magnetic path super-conductor excitation, automatic suspension and guiding of the high-speed linear propelling system mover is realized, and independent design of the propelling winding is achieved.

Description

technical field

[0001] The invention relates to a superconducting maglev linear electromagnetic propulsion system. It belongs to the motor field. Background technique

[0002] The existing high-speed maglev linear electromagnetic propulsion system can be divided into two categories: normal conduction type and superconduction type. The constant conduction type is also called the constant conduction magnetic suction type, represented by the German high-speed constant conduction maglev train transrapid, which uses the principle of electromagnetic attraction of ordinary DC electromagnets to suspend the train, and the suspended air gap is small, generally about 10mm. The speed of the conventional high-speed maglev train can reach 400-500km 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 mag...
