MTSF method
Opis:: In this paper, the new Modified Time Stepping Finite Element Method (MTSF) and Field- Circuit Method (FCM) for the inrusch current calculations of transformers have been presented. The computation time for MTSF and classical Time Stepping Finite Element Method (TSF) in 2D magnetic field analysis have been compared. The MTSF is about two times faster than the TSF method. We analyzed two constructions of the 1- phase transformers. The first one is amorphous modular core transformer (T1) and the second one is the conventional construction with laminated carbon steel core (T2). The comparision of the calculation and measurement results gives a good agreement.

Opis:: A method for modeling of the dynamics characteristics for a 5-phase permanent magnet tubular linear motor (PMTLM) is presented. Its electromagnetic nonlinear field analysis with finite element method (FEM) has been coupled with the circuit model. The calculation model includes the equations for electrical circuits and mechanical quantities as well. They have been obtained using Lagrange's method. The calculated and measured waves of the mover position have been compared for several values of the excitation current. This comparison yields a good agreement. Presented calculation model is very useful in designing and optimization of the PMTLM and in the calculation of the parameters for the control algorithms intended for such a type of actuators.
