Abstract

The invention provides an electromagnetic propulsion system for high-speed maglev transportation and a maglev train. The system comprises a linear motor and an electric suspension assembly. The linearmotor is used for accelerating and guiding the vehicle body. The linear motor comprises a first stator coil assembly, a second stator coil assembly, a third stator coil assembly, a fourth stator coilassembly, a first superconducting rotor coil assembly and a second superconducting rotor coil assembly. The first superconducting rotor coil assembly is positioned between the first stator coil assembly and the second stator coil assembly and is fixedly arranged on one side of the vehicle body. The second superconducting rotor coil assembly is positioned between the third stator coil assembly andthe fourth stator coil assembly and is fixedly arranged on the other side of the vehicle body. The electric suspension assembly is used for achieving automatic suspension of the vehicle body and comprises a permanent magnet array unit and a suspension induction plate, and the permanent magnet array unit and the suspension induction plate interact to generate suspension force. By means of the technical scheme, the technical problems that in the prior art, an electromagnetic propulsion system is low in thrust and poor in stability are solved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic propulsion, in particular to an electromagnetic propulsion system for high-speed maglev traffic and a maglev train. Background technique [0002] At present, the successful operation of high-speed maglev vehicles in Shanghai and low-temperature superconducting maglev vehicles in Japan has promoted the development of high-speed railways. The linear motor traction system used in maglev transportation can directly convert electrical energy into vehicle kinetic energy without intermediate transmission devices. In the field of high-speed railways It has a good application prospect. [0003] my country's Beijing Metro Capital Airport Line and Guangzhou Metro Lines 4, 5, and 6 all use linear induction motors for vehicle traction. The linear induction motor drive system installs three-phase windings under the car body, and uses the force between the eddy current generated by the induction plate l...
