본 발명은 청소기에 사용되는 모터의 회전자를 제작할때에 비자성체링의 내측에 설치되는 각각의 영구자석간의 간격을 이격유지시킬 수 있게 하는 모터 회전자의 영구자석 설치구에 관한 것이다.The present invention relates to a permanent magnet installation tool for a motor rotor that enables to maintain the spacing between each permanent magnet installed inside the nonmagnetic ring when manufacturing the rotor of the motor used in the cleaner.

일반적으로 모터의 균일한 자속 분포를 얻기 위해서는 각각의 영구자석이 균일한 간격으로 이격시킨 상태로 분할 고정시켜야 하는데, 영구자석을 균일한 간격으로 이격시킨 상태로 분할 고정시키기 위해서는 축이 설치된 요크의 외주연에 각각의 영구자석이 일정 간격을 균일하게 이격시킨 상태에서 각각의 틈새로 에폭시를 충진시켜 고정시켜왔다.In general, in order to obtain a uniform flux distribution of the motor, each permanent magnet should be divided and fixed at equal intervals. In order to separate and fix the permanent magnet at equal intervals, the shaft outside the yoke is installed. At the periphery, each permanent magnet has been fixed by filling an epoxy into each gap with uniformly spaced intervals.

상기 방법은 각각의 영구자석과 요크를 고정시키는 목적외에도 요크로의 손실자속을 줄일 수 있도록 비자성체인 에폭시를 사용하였으며, 아울러 영구자석 외주연에는 상기 손실자속을 줄이면서 영구자석의 이탈을 방지하기 위하여 비자성체링을 설치하고 있다.The method uses a non-magnetic epoxy to reduce the loss flux of the yoke in addition to the purpose of fixing each permanent magnet and yoke, and also in the outer peripheral edge of the permanent magnet to reduce the loss flux while preventing the permanent magnet from falling off For this purpose, nonmagnetic ring is installed.

종래에 모터의 회전자를 제작코져 비자성체링 내측에 영구자석을 일정 간격을 유지하며 배열 설치할때는, 비자성체링 내측에 착자되지 않은 영구자석을 접착제를 이용하여 고정하고 그 후에 착자하는 방법과, 착자된 영구자석을 갭 게이지를 이용하여 영구자석간의 균일한 간격을 잡은후 접착제를 도포하여 고정시키는 방법이 사용되어 왔다.Conventionally, when the rotor of the motor is manufactured and arranged in a non-magnetic ring inside the permanent magnet at a predetermined interval, the permanent magnet, which is not magnetized inside the non-magnetic ring, is fixed using an adhesive and then magnetized. A method of fixing a magnetized permanent magnet by using a gap gauge to uniformly space the permanent magnets and then applying and fixing an adhesive is used.

그러나, 상기와 같은 종래의 영구자석 배열 설치작업은 모두 정확한 위치를 유지하기가 곤란하였고, 접착제를 사용해야 하는 접착 작업상의 불편과, 접착제가 경화되는데 소요되는 작업시간을 지연과 그리고 이 모든 작업이 수작업에 의해서 이뤄지게 되므로 생산성이 극히 저조한 문제가 있다.However, the conventional permanent magnet array installation work as described above, it was difficult to maintain the exact position, the inconvenience of the adhesive work to use the adhesive, delay the work time required for the adhesive hardening and all these operations are manual Since it is achieved by the productivity is extremely low problem.

특히, 상기 영구자석을 비자성체링 내측에 일정 간격으로 배열설치하는 과정에서 영구자석의 상호간의 흡인력에 의해 각각의 영구자석간의 균일한 간격을 맞추기가 매우 어려워서 고정도의 모터를 생산하는데 어려움이 있었다.In particular, in the process of arranging the permanent magnets at a predetermined interval inside the non-magnetic ring, it is difficult to produce a highly accurate motor because it is very difficult to match the uniform intervals between the permanent magnets by the suction force of the permanent magnets.

따라서, 이 발명에서는 상기와 같은 종래의 제반문제점을 감안하여 이뤄진 것으로서, 이 발명의 목적은 모터의 회전자를 제작시 영구자석간의 틈새가 자동적으로 균일하게 맞추어질 수 있는 영구자석 설치구를 제공하여, 품질이 향상되는 회전자를 간편한 작업에 의해 양산할 수 있도록 하기 위한 것이다.Therefore, the present invention was made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a permanent magnet installation tool that can be automatically and uniformly spaced between the permanent magnets when manufacturing the rotor of the motor In order to achieve high quality, the rotor can be mass produced by a simple operation.

상기와 같은 목적을 달성하기 위한 이 발명의 특징은, 회전축에 설치된 요크 외주연에 각각의 영구자석들이 상호간에 일정 간격을 유지하면서 상기 요크와도 일정간격을 유지토록 설치한뒤에, 상기 간격에 에폭시를 충진시켜 회전자를 제작하는 영구자석 설치구에 있어서, 내주연에 상기 영구자석이 배열 설치되는 설치구의 몸체 전둘레에는 일정 간격을 분할하여 영구자석의 수량과 동일 갯수의 개구부가 형성된 모터 회전자의 영구자석 설치구에 있다.A feature of the present invention for achieving the above object is, after each of the permanent magnets on the outer periphery of the yoke installed on the rotating shaft to install a constant interval with the yoke while maintaining a constant distance from each other, the epoxy in the interval In the permanent magnet mounting tool for filling the rotor, the front circumference of the body of the mounting tool is installed in the inner periphery is divided by a predetermined interval of the motor rotor of the same number of openings and the number of permanent magnets are formed It's in the permanent magnet installation.
