Transient Simulation of Electrical Machines using Field-Circuit Coupled Method

摘要

In this paper, the transient simulations of electrical machines using a magnetic field-circuit coupled approach with diverse drive circuit topologies and two-dimensional finite-element analysis are described. A convenient approach to calculate the eddy loss of rotor bar in electrical machines is also presented. To illustrate the proposed methodology, this paper deals with three types of electrical machine including an interior-type permanent-magnet brushless DC motor, a single-phase induction motor and an asynchronous generator. The loss computations of these machines are carried out.
