Linear synchronous reluctance motors (LSynRM) have many advantages, such as low cost being due to elimination of permanent magnets, easy recycling, and so on. But they need to have complex suspension mechanisms because of the large attractive force. Therefore the magnetic suspension system is adopted in this study. In magnetic suspension systems, two independent windings are generally used for the propulsion and the magnetic suspension.
In this paper the LSynRM with magnetic suspension using armature winding for propulsion is proposed.The characteristics of the LSynRM with double side stator are analyzed by using the finite element method (FEM), and we consider magnetically-levitated location detection and aim the development of magnetically-levitated system without sensor. The system stability of speed control method using d-q current adjustment is examined. As a resut, mover posision in the y direction is approximately constant without sensor and in spite of velocity change.
