An induction generator having a pair of magnetic poles of the same polarity opposed to each other with respect to a rotation shaft is characterized by a high energy conversion efficiency. The induction generation has a rotation shaft driven by an external means; an even number of (more than three) stator cores provided to encircle the rotation shaft, predetermined gaps being provided between the adjacent stator cores; a first monopole rotor provided in the rotation shaft, surrounded by the even number of stator cores, and having first and second magnetic poles of the same polarity, the first and second magnetic poles being opposed to each other with respect to the rotation shaft in a cross section; a second monopole rotor provided in the rotation shaft so as to face the first monopole rotor at a predetermined distance along the rotation shaft, surrounded by the even number of stator cores, and having third and fourth magnetic poles of the same polarity opposite to the polarity of the first and second magnetic poles, the third and fourth magnetic poles being opposite to each other with respect to the rotation shaft; a plurality of windings provided in the even number of stator cores and connected according to a predetermined configuration.
