冷却方式のモータ。[Claims for Utility Model Registration] An outside air passage for cooling the outer surface of the stator is provided between the outer surface of the stator and a protective frame that covers the outer surface of the stator. , an inner fan for stirring the air in the stator is attached to a rotating shaft portion in the stator, and an inner fan is installed on the anti-load side of the rotor to cover an opening on the anti-load side of the stator. An outside fan is attached to the rotating shaft portion protruding from the bearing for sucking outside air from an outside air intake port provided on a side surface of a cover housing the protruding rotating shaft portion and sending it into the outside air passage. In a fan cooling type motor, one end is open to the outside air and the other end is used to supply outside air to the anti-load side bearing by using the negative pressure generated in the cover by the rotation of the outside fan. is the ventilation duct close to the anti-load side bearing,
A fan cooling type motor, characterized in that it is attached to the cover.
