In this paper authors are studying processes in electrical generators with rotors and stators with nonmagnetic shield with high coercitive permanent magnets. These generators can be used in hydroenergy and aerospace industry. In the paper there is developed a mathematic model allowing to analyze statical and dynamical characteristics of electrical generators with rotors and stators with nonmagnetic shield. To check the theoretical results there was made computer model in Ansys software. Authors got that results of mathematical models is comparable with the results of computer model.
