    The manufacturing process of the rotor of the switched reluctance motor according to the prior art described above has many problems. For example, a cost arises for manufacturing and developing molds for each component and the manufacturing cost increases due to a separate assembly process, which means that the manufacturing cost contributes to reduced competitiveness.
    SUMMARY OF THE INVENTION The present invention has been added with the intention of providing a switched reluctance motor which can reduce the manufacturing cost of a rotor by changing a molding process of surrounding plastic in which the rotor has a distinct pole construction.
    According to a preferred embodiment of the present invention, there is provided a switched reluctance motor, comprising: a rotor formed with a plurality of pronounced poles, a rotor core having the rotor coupled thereto; and a stop member formed into a continuous unit with the rotor core by a special insert casting method.
    The special insert molding process may be an injection molding process using a thermoplastic material or a thermosetting resin.
    The special insert molding process may be a process which uses an injection molding material.
    The special insert casting method may be a method of performing a press machining and then performing insert casting. At the time of mounting the stop element on the rotor core, an air gap can be 0.3t.
    The center part of the stop element, which is formed into a continuous unit with the rotor core by the special insert casting method, can be provided with the shaft.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The objects, features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments when taken in conjunction with the accompanying drawings. Throughout the accompanying drawings, the same reference numerals are used to indicate the same or similar components, and redundant descriptions thereof have been omitted. In the following description, the terms "first", "second", "one side", "the other side" and the like have further been used to distinguish a particular component from other components, but the design of such components should not be construed as a limitation. . Furthermore, in the description of the present invention, when it is considered that the detailed description of related technology obscures the context of the present invention, the description thereof shall be omitted.
    Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    Fig. 1 is an enlarged view of a rotor core 110 of a switched reluctance motor 100 according to a preferred embodiment of the present invention; and Fig. 2 is a view showing a mold in which a stator 120 and a rotor 130 of the switched reluctance motor 100 according to the preferred embodiment of the present invention are mounted together.
    Fig. 3 is an enlarged view of the rotor core 110 of the switched reluctance motor 100 according to the preferred embodiment of the present invention and a stop member 150 formed into a continuous unit with each other by insert casting. Fig. 4 is a view showing a configuration in which a shaft 160 is inserted into the center of a configuration in which the rotor core 110 of the switched reluctance motor 100 according to the preferred embodiment of the present invention and the stop member 150 are formed as a cohesive unit with each other through the insert casting.
    Fig. 1 is an enlarged view of a rotor core 110 of a switched reluctance motor 100 according to a preferred embodiment of the present invention.
    The rotor core 110 is formed mainly by press machining and then connected to a continuous unit with the stop element 150 by a special insert casting method.
    Fig. 2 is a view showing a mold in which a stator 120 and a rotor 130 of the switched reluctance motor 100 according to the preferred embodiment of the present invention are mounted together.
    The stator 120 comprises a plurality of pronounced poles 140 which have the task of fixing a rotating portion of the switched reluctance motor at an outer diameter thereof.
    The stator 120 is formed with a plurality of pronounced poles 140 projecting from the outer diameter thereof to an inner diameter thereof. The number of distinct poles 140 varies. Fig. 2 shows the case in which the stator 120 has eight distinct poles.
    The stator 120 is provided at the inner diameter with a rotor 130.
    The rotor 130 allows axial rotation of the motor and can be formed to have different shapes and poles according to a motor type. Fig. 2 shows the case in which the rotor 130 according to the preferred embodiment of the present invention has six phases. A mounted device in which the rotor 130 is mounted at the inner diameter of the stator 120, is mounted at a central portion of the rotor core 110 of Fig. 1.
    Fig. 3 shows the stop member 150 formed into a continuous unit with the rotor core 110 of the switched reluctance motor 100 according to the preferred embodiment of the present invention.
    The stator 120 and rotor 130 are mounted at a central portion of the rotor core 110 to form the rotor assembly.
    The rotor core 110 and the stop element 150 are formed as a continuous unit with each other by the special casting method, which reduces the number of manufacturing steps and the manufacturing time compared to a process according to the prior art, in which the rotor core and the stop element are separately formed and thus vertically mounted together. .
    Various methods of special casting of the rotor core 110 and the stop member 150 can be used. For example, an injection molding process using a thermoplastic material or a thermosetting resin can be used.
    In addition, a method using a molding material or a method of performing press production and then performing die casting can be used.
    At the time of mounting the stop member 150 with the rotor core 110, a small air gap may be 0.3t or less. When the air gap is maintained at 0.3t or less, abrasion due to the play of a mounted surface contact portion of the stop member at the time of high speed rotation of the rotor can be avoided. As stated above, with the switched reluctance motor according to the preferred embodiment of the present invention, the rotor core 110 and the stop element 150 are formed into a continuous unit with each other by the special insert casting method, so that the assembly time is reduced.
    As a result of an experiment, the assembly time has been reduced by 9.4 seconds per unit.
    In addition, the rotor core 110 and the stop element 150 are formed into a continuous unit with each other by the special casting method, so that the number of machinations is also reduced. In a result of an experiment, a separate recompression process to correct height, parallelism, and flatness after mounting the rotor core has been removed.
    It can be confirmed that the cost of 26.5 won is reduced per unit depending on the removal of the process, as a result of an experiment.
    Furthermore, a cost for manufacturing an unnecessary mounting jig has been reduced, and the number of manufactured casting units has been reduced from 3 to 2.
    Fig. 4 is a view showing the configuration in which the shaft 160 is inserted into the center of the configuration in which the rotor core 110 of the switched reluctance motor 100 according to the preferred embodiment of the present invention and the stop member 150 are formed as a continuous unit with each other by injection molding.
    When the switched reluctance motor 100 according to the preferred embodiment of the present invention has the above-mentioned design, the rotor core 110 and the stop element 150 are formed into a continuous unit with each other by the special insert casting method, thereby making it possible to reduce the assembly time, assembly process and assembly cost. . The special insert casting method can be applied to all motors as well as the switched reluctance motor. Although the embodiments of the present invention have been shown for illustrative purposes, it is to be understood that the present invention is not limited thereto, and those skilled in the art will recognize that various modifications, additions, and substitutions are possible without departing from the scope and spirit of the invention.
    Thus, any and all modifications, variations and equivalent arrangements are to be considered within the scope of the invention, and the detailed scope of the invention is set forth in the appended claims.
