The no-load electromagnetic field of an introduced type of 4-pole half-speed nuclear power generator is calculated and analyzed by finite-element method. The results of wave forms of no-load flux density, air-gap flux density and no-load voltage are obtained. On this basis, no-load field current of this type of generator is calculated and stator voltage distor-tion rate is analyzed by Fourier decomposition method. The calculation results are in conformity with test results, which verifies accuracy and reliability of this method.
