The present invention relates to an induction motor having multi-stage rotors arranged concentrically and being usable as a generator. More particularly, the present invention relates to an induction motor, which includes a core having conductive bars arranged in multi stages and coils arranged in multi stages, and which is usable as a generator. The present invention may be applied to a hub type, in which a shaft is fixed and a housing of the induction motor is rotated, and a rotation type, in which the housing is fixed and the shaft is rotated. According to one aspect of the present invention, the induction motor according to the present invention includes a rotor and a stator. Here, the rotor includes a plurality of cylindrical cores arranged in multi stages in a radial direction, each of the cores having a plurality of grooves formed in an axial direction on a periphery thereof and arranged along a circumferential direction, and a plurality of conductive bars inserted into the grooves of the core of each stage. In addition, the stator includes armature cores arranged in one or more stages in a radial direction to face the periphery having the grooves formed thereon, and a plurality of armature coils wound around the armature cores to correspond to the respective conductive bars.
