Abstract

This paper deals with the determination of the end winding inductance of a permanent-magnet linear synchronous motor (PMLSM). The methods to determine the inductances in three dimensions are given for both classical complementary formulations. In a first step, an elementary cell of the structure is modeled using both methods and the results are analyzed and discussed. In the second step, the complete structure is studied in two and three dimensions using only the scalar potential formulation to limit the computation time. The numerical results are compared with experimental ones.
