Large turbo-generator end electromagnetic field and temperature field calculating method

The invention discloses a large turbo-generator end electromagnetic field and temperature field calculating method. The method is characterized in that the method comprises the steps of establishing acalculation model, establishing an end electromagnetic field distribution calculation module, establishing a temperature field distribution calculation module and carrying out result analysis and thelike. Through calculation based on electric-thermal sequential coupling analysis technology, the method allows a designer to predict whether temperature rise of a generator end magnetic field and anend structure member is within the permissible limit of an insulation material and a metal material, so that reasonability of the design structure and material selection is verified; the calculation process is modular, so that the calculation process is easy to use and easy to modify, and can be called repeatedly; and through a sequential coupling calculation mode, scale in solving an equation isreduced, and calculation spe
