A Detailed Lumped-Parameter Method for the Study of Electrical Machines in Transient Stability Studi magnetic circuits of the machine are represented by components calculated from design data. Magnetic capacitors or magnetic admittances are defined to represent the magnetic flux paths in the machine and the effects of eddy currents in the dampers and rotor iron are represented by magnetic resistor

The Electromagnetic Field of an Insulated Conductor in a Slotiron core and the remaining side is open. The insulated conductor, also infinite in length and of rectangular cross-section, is entirely within the slot. A current, varying sinusoidally with time, flows in the axial direction. Such a configuration occurs in practice in the design of slot wound elect

CAD Aspects of Electromagnetic Field Calculationsst this purpose. Indeed, there are still those ancient stalwarts who insist that “nothing is faster than their slide-rule”. However, times and techniques are changing, and it appears to be generally agreed that with careful planning, modern CAE methods can produce increased benefits and profits.

Simulation of Hysteresis in Ferromagnetic Materialsacy. However, hysteresis must be included in the modelling of permanent-magnetic-type materials or with any ferromagnetic material when the hysteresis loss is a substantial part of the total core loss. A wide range of problems require the dynamic modelling of hysteresis. These cover the whole spectr

The Extraction of Engineering Information from a Potential Solution to an Electromagnetic Field Probx devices. The complexity may be introduced by the geometric shape, the material properties, time dependence or a combination of all of these. Traditionally, these devices have been designed using a mixture of simplified, algebraic, closed form solutions, experimental evidence and design experience.
