Electromagnetic Analysis and Optimization of High-speed Maglev Linear Synchronous Motor Based on Field-circuit Coupling

High speed maglev train has become a new non-contact transportation mode mainly studied in recent years because of its non-sticking and high speed characteristics. Firstly, the finite element model of the long stator linear synchronous motor(LSM) is established based on the structure of the test prototype. After calculation, it is compared with the experimental data and verified. On this basis, a field-circuit coupling model based on inverter circuit is established, and the influence of carrier wave ratio change on the output characteristics of LSM is calculated and analyzed. Finally, the filter circuit is introduced into the field-circuit coupling model, and the influence of the filter circuit on the output characteristics of the LSM is compared and analyzed.
