By means of the classical method of the magnetic circuit analysis, the no load characteristic calculation model of the hybrid excitation rare earth permanent magnet synchronous generator (simplified as HESG) is established. The relevant program in an advanced program language MATLAB has been brought forward and used in this paper. The effect of the leakage flux on the no load characteristic of the HESG has also been analyzed. A 1.5kVA prototype of this new generator has been tested and calculated. The comparison of the no load characteristic data shows that the calculation model can meet the requirement for the engineering precision.
