特徴とするかご形誘導電動機の冷却装置。In a cooling system for a squirrel-cage induction motor, in which multiple axial ventilation ducts are provided on the stator side and the rotor side, and internal air is circulated using an internal fan, cooling air is supplied to one side of the rotor in the motor when the rotating shaft rotates in the forward direction. A centrifugal internal fan is installed on the other side of the rotor that generates cooling air toward the outer circumference and generates cooling air toward the inner circumference during reverse rotation. An axial-flow internal fan is provided with inclined blades that generate cooling air toward the rotor core side during reverse rotation, and at least the end face of the short-circuit ring on the axial-flow internal fan side is connected to the inner peripheral side. A cooling device for a squirrel-cage induction motor, characterized in that it is constructed with a low slope surface.
