This paper presents two-dimensional field-circuit model of 500 MVA turbogenerator. Model is designed to calculate static and dynamic characteristics of machine. During solving field equations real physical characteristics of materials, configuration of windings, damper circuit and motion elements in electromagnetic field are taken into account. In circuit part there is an electrical scheme. The electrical...
Optimization of geometry is the one of the most important process in the electrical motor design. Among of the various design parameters tooth and yoke width are the dominate variables that can maximize he back electromotive force (Back-EMF) and on-load torque. In this paper, in order to design the tooth and yoke width effectively, an equivalent magnetic circuit used to calculate the reluctance is...
A field-circuit coupling method is presented, whose basic idea is to extract from the FE model, on basis of energy balance considerations, a temporary lumped parameter representation of the electrical machines, to be used in the circuit simulator model of the power electronic supply. The dynamic coupled model of the complete drive obtained this way can be iterated over a limited period of time, with...
