Abstract

Analytical expressions for determination of inductive resistance on long and cross axes of synchronous electrical machines with permanent magnet excitement and repetition factor of short circuit current are received where effect from electromagnetic loadings, polar system dimension and other parameters is possible to estimate at a stage of design calculation. Also the choice of these relative independent variables can be made taking into account the required repetition factor of short circuit current and stability of permanent magnet properties.
