The study of magnetic anisotropic key elements for the traction motor control system

The magneto-anisotropic key element and its mathematical model are studied in the two dimensional space. The magnetic conductor under control is replaced with an equivalent wafer in the electromagnetic field affected by force action; the wafer's mathematical model is described as the system of differential equations according to the electromagnetic field theory, ferromagnetism, and the elasticity theory. For the key magnetic circuit there is an equivalent circuit which is represented by the system of algebraic equations. The solution of differential and algebraic equations enables us to identify electric and magnetic parameters of the key and to build its output statiс characteristic.
