Self-magnetization method for motor except the magnetizator is carried out as follows; 1) leading current of magnetization coil carries magneto-energy from the stator in order to operate the increasing magnetism primarily 2) and this current is rectified and transformed into field current to make the secondary steady magnetic field directly, 3) and one type leading magnetization current carries out double magnetization operation, 4) and the field current flows out by rectifying the leading current which leads 90 degrees more than the induced electromotive force.
