The method includes the step of producing an electro-magnetic rotor, the step of producing a permanent magnet rotor and the step of assembling the rotors. The electro-magnetic rotor is of a protruding pole structure, the generated magnetic field directly faces towards an air gap, and the leakage flux is little. A long T-shaped protruding pole and a short T-shaped protruding pole are isolated from each other and arranged on the periphery of a rotor iron core of the permanent magnetic rotor. A piece of arc-shaped permanent magnet steel is fixed to the short T-shaped protruding pole, and the polarity of an inner arc face, close to the short T-shaped protruding pole, of the arc-shaped permanent magnet steel is led onto the long T-shaped protruding pole through the rotor iron core so that the combined type invisible magnetic pole rotor with the N pole and the S pole being arrayed in a spaced mode can be formed. The two polarities of the arc-shaped permanent magnet steel are fully used, the material utilization rate is high, the magnetic field in the air gap of a generator is supplied by an electric excitation coil and the permanent magnet steel together, the magnetic field can be adjusted, and the output voltage of the generator is stable.
