A totally enclosed motor which includes a rotor disposed inside a housing and a heat of the rotor is transferred to the housing, a stator disposed inside the housing and a heat of the stator is transferred to the housing, and an inner fin which is disposed in the rotor and agitates air inside the housing. The totally enclosed motor is cooled by a forced convection by an outer fan disposed outside the housing, or by a natural convention in the vicinity of an outer surface of the housing, and a shape of the rotor is different between one end side and the other end side of the rotor in an extending direction of a rotary shaft of the rotor.
