The embodiment of the invention discloses an AC/DC hybrid excitation type motor power generation system, relates to a hybrid excitation motor power generation technology, and can reduce the external excitation power required by the power generation system and reduce the capacity of an excitation power circuit and the weight of a controller. The system comprises an AC-DC hybrid excitation type motor and a generator controller. The AC-DC hybrid excitation type motor comprises a stator excitation reluctance motor and a permanent magnet motor. A first armature winding of the stator excitation reluctance motor and a first armature winding of the permanent magnet motor are connected in series and then are connected with the bridge type uncontrolled rectification circuit to form a main power output circuit of the power generation system; a direct current excitation winding of the stator excitation reluctance motor is connected with an excitation power circuit to form a direct current excitation circuit of the power
