USE OF SCALAR SINGLE AND DOUBLE LAYER POTENTIALS IN THE PROBLEMS OF IDENTIFICATION OF PERMANENT MAGNETS IN THE LINEAR SYNCHRONOUS MOTORS
The paper presents the development of the method for identification of the permanent magnet remanence using the measured values of magnetic flux densities. The base method is generalized on a case of existence of several magnets and ferromagnetic. Identification method is based on solving the ill-conditioned system of equations by using the regularization method. The method of secondary sources is used with scalar single and double layer potentials for the constructing the matrix of system. The element of rotor of the linear synchronous motor is under discussion as an example of the proposed method application. The analytical formulas for the matrix of system are obtained for this construction. It is make a possible to simplify the regularization method. The software is developed for the verification of the proposed method. The software allow to model measurement of the flux density by solving the magnetic field analysis problem and by making the inaccuracy injection, that is the unavoidable thing in the process of real measurements of flux density. After that the proposed identification method is used.
