Abstract: --A hybrid excitation starter for an internal combustion engine comprises a machine housing, an armature, and an electrical excitation structure and a permanent magnet structure provided in the machine housing, and the electrical excitation structure comprises a plurality of electrical excitation magnetic poles and excitation coil windings. The electrical excitation magnetic poles are uniformly mounted on the machine housing corresponding to the armature and air gaps are formed between the electrical excitation magnetic poles and the armature; the permanent magnet structure comprises a plurality of permanent magnet magnetic poles, which are provided corresponding to the electrical excitation magnetic poles, and are mounted on the machine housing or the electrical excitation magnetic poles respectively, and a magnetic potential formed by coupling the electrical excitation magnetic poles and the permanent magnet magnetic poles together forms a closed magnetic flux linkage by means of the machine housing, the armature and the air gaps.--
