Abstract: The present invention relates to a module for cooling a heating element and a motor including the same. The module for cooling the heating element, according to the present invention, can comprise: a flat plate-shaped heat pipe containing working fluid therein, coming into close contact with the heating element, and including a condensation region which does not come into contact with the heating element; and a cooling channel connected to the condensation region, and cooling the heat pipe by a refrigerant.

Abstract: A stepping motor is disclosed, configured in such a manner that a cover is hitched by a hitching protruder of a housing to allow the cover to be coupled to the housing, or the cover is hitched by a caulking unit of the housing to allow the cover to be coupled to the housing, whereby the problem of parts being damaged by using adhesive can be reduced or eliminated because the adhesive is not used in coupling the cover. In addition, bending of the hitching protruder of the housing or caulking of a surface of the housing allows the cover to be coupled to the housing, whereby assembly time can be shortened to enhance the productivity.

Abstract: A stepping motor is provided. The stepping motor comprises a bracket, a lead screw having a first side rotatably supported by the bracket, and a housing. A second side of the lead screw is disposed in the housing such that the lead screw is rotatably supported thereto, and a portion of the bracket is inserted into the housing so as to be coupled with the housing. A stator is installed in the housing, and a rotor is coupled with the lead screw to interact with the stator for rotating the lead screw.
