Description

DC 모터의 계자권선 절연장치 ( An apparatus for insulating field coil of DC motor )An apparatus for insulating field coil of DC motor

본 고안은 DC 모터의 계자권선을 절연시키는 장치에 관한 것으로, 특히 계자권선과 모터의 외피를 이루는 프레임 또는 계자권선이 조립되는 고정자 사이를 절연시켜 계자권선을 효과적으로 보호할 수 있도록 된 DC 모터의 계자권선 절연장치에 관한 것이다.The present invention relates to a device for isolating the field winding of the DC motor, in particular the field of the DC motor that can effectively protect the field winding by insulating between the field winding and the stator to which the frame or field winding forming the outer shell of the motor is assembled The present invention relates to a winding insulation device.

일반적으로 DC 모터는 자극을 고정자(stator)로 하고 전기자를 회전자(rotor)로 하는 방식과, 전기자를 고정자로 하고 자극을 회전자로 하는 방식이 있는 바, 전자의 경우 자극인 고정자측에 코일(이하, 계자권선이라 한다.)이 가긴 구조로 되어 있어서, 계자권선에 전류가 흐르면 암페어(Ampere)의 오른나사법칙에 의해 자극철심이 자화되어 전류방향에 따라 극(N 또는 S)을 만들고 이러한 자계형성은 회전자에 토오크를 발생시켜 회전시키게 되므로, 모터가 회전하게 된다.In general, DC motors have magnetic poles as stators and armatures as rotors, and armatures as stators and magnetic poles as rotors. (Hereinafter referred to as field winding), when current flows in the field winding, magnetic pole is magnetized by Ampere's right-handed law to make pole (N or S) according to the current direction. The magnetic field is rotated by generating torque in the rotor, so that the motor rotates.

상기한 바와 같은 자극을 고정자로 하고 또한 고정자가 적층된자극철심으로 이루어지는 모터는, 소정 형상의 자극철심에 코일 다발로 된 소정 형상의 계자권선을 각각 조립한 고정자부분을 이루도록 되어 있고, 이와 같이 자극철심에 조립된 게자권선과 모터의 외피를 이루는 프레임 또는 계자권선에 조립되는 고정자사이를 절연시켜 계자권선이 조립되는 고정자사이를 절연시켜 계자권선을 보호할 수 있도록 되어 있다.The motor made of a magnetic pole as described above with a magnetic pole as a stator and a stator laminated thereon constitutes a stator portion in which magnetic field windings of a predetermined shape made of coil bundles are respectively assembled to a magnetic pole having a predetermined shape. Insulation between the magnetic windings assembled in the iron core and the stator assembled in the frame or the field winding forming the outer shell of the motor is insulated from each other to protect the field windings.

이와 같이 계자권선을 절연시켜 계자코일을 보호하는 종래의 방법은, 소정 형상으로 감겨진 계자권선 표면을 따라 유리섬유와 같은 절연재질로 된 절연테이프를 감은 다음, 절연유에 함침시켜 이루어지도록 되어 있다.The conventional method of protecting the field coils by insulating the field windings is performed by winding an insulating tape made of an insulating material such as glass fiber along the surface of the field winding wound in a predetermined shape and then impregnating it with insulating oil.

그런데, 상기와 같이 이루어지는 종래의 절연방법은 절연테이프를 감을 때 감긴 수가 일정치 않거나 테이프들이 서로 중첩되는 등에 의해 전체두께가 불균일하여 자극철심에 조립하기가 어려울 뿐만 아니라 조립과정중에 절연테이프가 벗겨져 절연파괴의 원인이 된다는 문제점이 있었다.By the way, the conventional insulation method made as described above is difficult to assemble the magnetic poles due to the irregular thickness or the total thickness is uneven due to the overlapping of the tapes, such as overlapping each other, as well as insulation tape peeled off during the assembly process There was a problem that causes destruction.

이에 따라 감겨지는 절연테이프의 중첩 부분을 줄이면서도 절연을 확실하게 하기 위해서는 계자권선 전체를 균일하게 감아야 하는 번거로움이 발생되어, 절연작업에 소요되는 시간이 많아지게 된다는 문제점이 있었다.Accordingly, in order to ensure the insulation while reducing the overlapping portion of the insulation tape to be wound, the trouble of having to wind the whole field winding uniformly is generated, and the time required for the insulation work is increased.

이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 소정형상으로 절곡성형된 절연재를 통해 계자권선을 간편하게 절연시켜 절연작업에 소요되는 시간을 줄일 수 있음과 더불어 계자권선을 효과적으로 보호할 수 있도록 된 DC 모터의 계자권선 절연장치를 제공하는 데 그 목적이 있다.Therefore, the present invention has been devised to solve the above problems, and it is possible to effectively insulate the field winding by insulating the field winding through an insulating material bent to a predetermined shape and to effectively protect the field winding. The purpose is to provide a field winding isolator of a DC motor.

상기와 같은 목적을 달성하기 위한 본 고안은, 계자권선의 절연부위를 감싸줄 수 있도록 소정형상으로 절곡성형된 절연재가 긴밀하게 결합되어 자극철심에 삽입되어지도록 되어 있다.The present invention for achieving the above object, the insulating material bent to a predetermined shape to cover the insulating portion of the field winding is tightly coupled to be inserted into the magnetic pole core.

상기와 같이 이루어진 본 고안의 계자권선 절연장치에 따르면, 소정형상으로 절곡성형된 절연재를 계자권선에 끼운 다음 자극철심에 조립하면 되므로 절연작업에 소요되는 시간을 줄일 수 있게 된다.According to the field winding insulation device of the present invention made as described above, it is possible to reduce the time required for the insulation work by inserting the insulating material bent into a predetermined shape in the field winding and then assembled to the magnetic pole core.
