Electric-power generation all-in-one machine with radiator fan for tractor

The invention provides an electric-power generation all-in-one machine with a radiator fan for a tractor. The electric-power generation all-in-one machine is composed of a shaft, the radiator fan, a bearing, a motor end cover, two rotor cores, two armature windings, a stator core, excitation windings, a shell and a belt pulley. The two disk-shaped rotor cores are respectively fixed on the shaft, and 4N circular ring fan convex rotor poles are arranged on one surface opposite to the stator core of each rotor core. The stator core fixed on the shell is composed of four fan-shaped modules which are uniformly distributed in the circumferential direction, and one excitation winding is twisted along the axial center of each fan-shaped module. Three stator poles are arranged on an end face of each fan-shaped module, and each stator pole is provided with a first armature winding. The radiator fan is fixed at a tail end of the shaft. When the electric-power generation all-in-one machine works in a motor mode, a motor
