Abstract A turbogenertor without damper cage is divided into five regions according to compoding materials in the radial direcrion. And the electric and magnetic field of each region in the subsynchronous resonance (SSR) phenomena is analyzed in this paper. The analytical method is based on solving a boundary value problem involving a three-dimensional magnetic diffrsion equation and the basic function consists of the double Fourier series. And the electrical characteristics of the material and kthickness of the wedges inserted in slot of the region III, which is dependent on frequency, is to be investigated.
