PROBLEM TO BE SOLVED: To obtain a hybrid excitation type synchronous machine in which the overall size is reduced, magnetic saturation is not present and high speed rotation is enabled. SOLUTION: This synchronous machine has a stator 21 and an armature 11. In a stator 21, a rotor back yoke 4 is fixed to a shaft 15. An exciting winding 5, which is wound along the peripheral direction, is embedded in the back yoke 4. Two of a plurality of armature cores 2 are fixed in a line in the axial direction on the outer periphery of the back yoke 4. In the armature 11, core salient poles 12a and permanent magnets 13 are arranged alternately in the peripheral direction, facing the core 2 via a gap, outside the stator 21 and inside the back yoke 14. The permanent magnets 13 are so arranged that the N pole side and the S pole side are divided in the axial direction. The permanent magnets 13 are so arranged alternately that the N pole sides and the S pole sides are not arranged side by side in the axial direction.
