Abstract

The invention relates to a high-speed magnetic levitation linear electromagnetic propulsion system and belongs to the electric motor field. The invention aims to solve the problem of serious magneticflux leakage due to the openness of a magnetic field and the problems of small levitation height, large levitation control difficulty and high requirements for lines of a normal conducting magnetic levitation technology due to large weight of vehicles. The high-speed magnetic levitation linear electromagnetic propulsion system of the invention a primary unit and a secondary unit; the primary unitis mounted on the ground, is of a bilateral structure and is arranged symmetrically on the left side and right side of the secondary unit; air gaps are left between the primary unit and secondary unit; the primary unit comprises a levitation guide primary unit and a propulsion primary unit; each primary structure at each side of the propulsion primary unit includes a primary coil and a primary substrate, wherein the primary coil is fixed at the inner side of the primary substrate; each primary structure at each side of the levitation guide primary unit includes an upper conductor plate and a lower conductor plate, wherein the upper conductor plate and the lower conductor plate are juxtaposed in a vertical direction; the propulsion primary unit is arranged between the upper conductor platesand the lower conductor plates; two columns of magnetic poles of the primary unit are respectively fixed at two sides of a skid; and each column of magnetic poles simultaneously serves as levitationguide magnetic poles and propulsion magnetic poles.

Description

technical field [0001] The invention belongs to the field of motors. 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 magnetic field generated by superconducting magnets, and interacts with the coils...
