A closed slot outer-rotor type induction motor is provided to improve vibrational property of a motor due to eccentricity between a rotor and a stator by excluding a slot exposing a conductor bar. A closed slot outer-rotor type induction motor comprises a stator and a rotor(100). A plurality of slots are arranged in the circumference of a stator core to columnar direction. A coil is wound in a plurality of slots. A plurality of conductor bars(120) are arranged in the inner circumference of a rotor core(110) to columnar direction. The inner circumference of rotor has the outer circumference and air gap of the stator and is faced. The rotor rotates in the outer side of the stator. The conductor bar is laid inside the rotor core. A slot exposing the conductor bar is excluded.
