The invention provides a hybrid excitation compensation pulse generator which relates to a hybrid excitation generator, belonging to the motor field. The invention aims to solve problems in the prior compensation pulse generator, such as complicated electrical excitation structure and unadjustable permanent magnet excitation output. A stator core of the invention is divided into two sections along the axial direction; an exciting winding is arranged between the two sections of the stator core which are fixed on the inner wall of a stator back yoke respectively; an armature winding is arranged inside the stator core; a rotor back yoke is fixed on a main shaft, having an external surface fixed with a rotor core; an external surface of the rotor core is divided into two zones which are alternately distributed with permanent magnets and ferromagnetic bodies respectively along the circumference; polarities of the permanent magnets are the same in the same zone and opposite in different zones; and the permanent magnets-ferromagnetic bodies are alternately arranged along the axial direction, and are provided with aluminum compensation cylinders on external surfaces. The other proposal is as follows: the external surface of the rotor core is divided into two zones which are alternately distributed with the permanent magnets and combined blocks of the permanent magnets and the ferromagnetic bodies respectively along the circumference; and adjacent permanent magnets have opposite polarities; the alternate arrangement is performed along the axial direction according to the sequence of permanent magnet-ferromagnetic body-permanent magnet, and alternately-arranged permanent magnets have the same polarity.
