Résumé

The superconductors are exceptional materials; they have the advantages of zero resistance, trapping of strong magnetic field intensities, and ability to carry very high current densities. Now, the superconductors can be practically used in electrical engineering devices in two main forms: coils and bulk magnets. The HTS bulks magnets can trap a magnetic field above 2.3 T at 77 K [1].
Field cooled FC or zero-field-cooled ZFC magnetization are the two popular procedures to obtain a magnetized HTS bulks [2]. Considering the characteristics of this kind of materials, they strongly enter to the applications of electrical power and its devices (transformers, electrical
machines, energy storage, cables … etc).
In this work, we will study the electromagnetic behavior and thrust characteristics of a synchronous linear motor (LMS) with HTS bulks magnets in its secondary (mover), and a conventional copper wire in the primary part (3ϕ windings). The motor will be modeled numerically using
the 2D finite element method (2D-FEM).
The no-load and load characteristics of the motor were also analyzed. To show the HTS-Magnet advantages, we carried out a comparative study between our proposed HTS-LMS and a conventional PM-LSM.
It should be noted that the 2D-FEA is carried out by the commercial simulation software: FEMM®.
