Abstract:

A numerical technique for determining the end leakage reactance of electrical machines is described. The three-dimensional distribution of electromagnetic fields is obtained from the partial differential equation for the vector potential. Because of geometric irregularities, 18-point difference formulae are derived to approximate this equation, and are used to obtain its solution. A moded is developed based on a 95 KVA, 3-phase, 115200 volt, 3400 cps, homopolar inductor alternator. Two connected, dissimilar grid systems, to which the difference formulae are applied, are superimposed on the model. Boundary conditions, their difference analogues, and the representation of volume distributed currents are discussed. A computer program, from which the potentials are obtained, is described. Author
