An induction motor includes: a stator in which a plurality of winding coils wound in a central direction of a stator core are arranged; an induction rotor rotatably inserted into the stator; and a synchronous rotor including a magnet and rotatably inserted into an air gap between the stator and the induction rotor, so that the induction motor reduces the size of the whole motor and has a structure of a compact size to thereby reduce installation space and manufacturing cost and increase output power and efficiency.
