“…Besides that, this LIM topology was projected to increase the levitation force during the traction, due to the attraction force between the primary and secondary. More details about this motor were presented in previous work [9]. Table I shows the characteristic of the LIM.…”

This paper describes the construction and main components of a full-scale superconducting magnetic levitation vehicle. The prototype, comprising four 1.5-m-long wagons, will travel a short test line of 200 meters, connecting two buildings inside the campus of the Federal University of Rio de Janeiro. The efforts to implement this technology started thirteen years ago with a small-scale prototype in an attempt to prove the concept. The second step was the construction of a functional prototype that could levitate more than one Ton. The actual stage of this project is the construction of an operational prototype mentioned above, designed to transport up to 24 passengers. This work has been reported in several previous editions of the ASC conference. New details about the elevated test line, the permanent magnetic (Nd-Fe-B) guideways, the cryostats with YBCO high critical temperature superconductors, the energy conditioning, the linear induction motor and its regenerative braking, as well as the automatic supply system of liquid nitrogen will be presented in the proposed paper. Tests with this operational prototype demonstrate the technology feasibility.

“…During the experiments with only one module [7]- [9], the 4 or 6 cryostats were filled with liquid nitrogen manually for the tests. As the vehicle has 24 cryostats, the manual fill of all these would take considerable time, or many people working at the same time.…”

“…Due to the unique stable levitation property, high temperature superconductors (HTS) have exhibited a great potential for the industrial applications in magnetic levitation (Maglev) systems, such as contactless bearings [1][2][3], and levitated transportation systems [4,5]. It is known that the magnetic levitation and guidance forces result from the interaction of the HTS and the permanent magnet guideway (PMG).…”

Abstract-This paper presents a new analytical method for predicting magnetic field distribution and levitation force in three configurations of high temperature superconducting (HTSC) maglev vehicles. The permanent magnet guideways (PMG) are composed with ferromagnetic materials and NdFeB permanent magnets. The proposed analytical model is based on the resolution in each region of Laplace's and Poisson's equations by using the technique of separation of variables. For the study, we consider the HTSC as a perfect diamagnetic material. The boundary conditions and Fourier series expansion of interfaces conditions between each region are used to find the solution of magnetic field. The developed analytical method is extended to compute the magnetic field distribution generated by the three types of PMGs when removing the HTSC bulk. Magnetic field distribution and vertical force obtained analytically are compared with those issued from the finite element method (FEM).
