Abstract

The invention provides an electromagnetic propulsion system and a maglev train for high-speed maglev traffic. The system includes a linear motor and an electric suspension assembly. The linear motor is used to realize the acceleration and guidance of the vehicle body. The linear motor includes first and second stators Coil groups, third and fourth stator coil groups, first and second superconducting mover coil groups, the first superconducting mover coil group is located between the first stator coil group and the second stator coil group and is fixedly arranged On one side of the car body, the second superconducting mover coil group is located between the third stator coil group and the fourth stator coil group and is fixed on the other side of the car body. The electric suspension assembly is used to realize the automatic movement of the car body. Suspension, the electric suspension component includes a permanent magnet array unit and a suspension induction plate, and the permanent magnet array unit interacts with the suspension induction plate to generate suspension force. The technical solution of the invention is applied to solve the technical problems of low thrust and poor stability of the electromagnetic propulsion system in the prior art.

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...
