A double-voltage hybrid excitation earth rare permanent magnet synchronous generator is designed is this paper. There are two windings in its stator, and its rotor consist of permanent magnet and electrical excitation windings. It takes the advantage of electrically excited and permanent magnet synchronous generator. The structure principle and electromagnetism calculation are detailedly analyzed. A model for electromagnetic calculation and formulas for voltage are obtained by dealing with the d-q axis electromagnetic coupling of the double- winding armature reaction. it is verified to be accurate by the comparison of the results of design and test.
