Description

플라스틱 패키징 직류 브러시레스 전동기의 고정자{STATOR STRUCTURE OF PLASTIC PACKAGED DC BRUSHLESS-MOTOR}Stator of plastic packaging direct current brushless motor {STATOR STRUCTURE OF PLASTIC PACKAGED DC BRUSHLESS-MOTOR}

본 발명은 플라스틱 패키징 직류 브러시레스 전동기의 고정자에 관한 것이다. The present invention relates to a stator of a plastic packaging direct current brushless motor.

종래의 플라스틱 패키징 직류 브러시레스 전동기의 고정자 내부에 일반적으로 SMD(Small mounted device) 타입의 홀소자가 장착되어 전동기의 회전속도를 측정하지만, 플라스틱 패키징 하우징에 SMD 타입의 홀소자를 배치하고 위치를 고정하기 어려우며 신호 민감도와 측정의 정확도가 떨어진다. 한편, 고정자 권선과 고정자 철심을 격리시키기 위하여 일반적으로 고정자 철심의 단면에 절연 단부를 형성할 것을 요하지만, 전동기에 대해 플라스틱 패키징 사출공정을 진행할 때, 종래의 절연단부 부품에 플라스틱 패키징 재료가 견고하게 결합되지 못하고 쉽게 탈락되는 문제점이 존재한다. In the stator of the conventional plastic packaging DC brushless motor, a small mounted device (SMD) type Hall element is generally mounted to measure the rotational speed of the motor, but it is difficult to arrange and fix the SMD type Hall element in a plastic packaging housing. Signal sensitivity and measurement accuracy are poor. On the other hand, in order to insulate the stator winding and the stator iron core, it is generally required to form an insulating end in the cross section of the stator core, but when the plastic packaging injection process is performed on the motor, the plastic packaging material is firmly attached to the conventional insulated end part. There is a problem of not being combined and easily dropped.

본 발명의 목적은 용이하게 센서를 설치할 수 있고 센서의 측정 정확도를 향상시킬 수 있는 플라스틱 패키징 직류 브러시레스 전동기의 고정자를 제공하는데 있다. An object of the present invention is to provide a stator of a plastic packaging direct current brushless motor which can easily install a sensor and improve the measurement accuracy of the sensor.

본 발명은 다음과 같이 구현된다. The present invention is implemented as follows.

본 발명에 따른 플라스틱 패키징 직류 브러시레스 전동기는 고정자 철심과, 고정자 철심에 씌워진 절연단부와, 절연단부에 감겨진 코일권선과, 고정자 철심, 절연단부 및 코일권선 상에 플라스틱 사출방식으로 형성된 하우징을 포함하며, 하우징 내에 챔버가 형성되어 있고, 챔버 상부의 하우징 내벽에 센서를 수용하는 오목홈이 형성되어 있다. 따라서 챔버 상부의 하우징 내벽에 형성된 오목홈에 센서를 설치할 수 있으므로 설치작업을 편리하게 수행할 수 있고 견고하게 고정할 수 있으며 센서의 측정 정확도를 향상시키고 고정자 내부의 한정된 공간을 충분히 이용할 수 있다. The plastic packaging DC brushless motor according to the present invention includes a stator core, an insulation end covered by the stator core, a coil wound around the insulation end, and a housing formed by a plastic injection method on the stator iron core, the insulation end, and the coil winding. A chamber is formed in the housing, and a recess is formed in the inner wall of the chamber to accommodate the sensor. Therefore, the sensor can be installed in the concave groove formed in the inner wall of the upper chamber of the chamber, so that the installation work can be conveniently performed and securely fixed, and the measurement accuracy of the sensor can be improved and the limited space inside the stator can be sufficiently used.

오목홈은 2개 이상이며 직사각형 홈으로서 용이하게 가공할 수 있다. 그리고 오목홈 내에 위치한 센서는 홀(hall) 소자 플러그이며 편리하게 사용 및 설치할 수 있다. Two or more recessed grooves can be processed easily as a rectangular groove. And the sensor located in the concave groove is a hall element plug and can be conveniently used and installed.

절연단부의 윗면으로부터 전면 차단막과 후면 차단막이 연장 설치되고 전면 차단막과 후면 차단막에는 모두 오목한 홈이 형성되어 있고 홈 뒷면에는 전후를 연 통하는 채널이 형성되어 있다. 전동기에 대해 플라스틱 패키징 사출공정을 진행할 경우 플라스틱 패키징 재료가 홈 안으로 유입되어 홈을 채우게 된다. 그리고 플라스틱 패키징용 재료는 홈의 뒷면 채널로부터 전면 차단막과 후면 차단막의 뒷면에 흘러들어 전면 차단막과 후면 차단막의 앞면과 뒷면을 덮는다. 따라서 전반 구조의 연결강도를 향상시킬 뿐만 아니라 전면 차단막과 후면 차단막 부품에 플라스틱 패키징된 재료가 쉽게 탈락되지 않도록 한다. The front and rear barriers are extended from the top of the insulating end, and both the front and rear barriers are formed with concave grooves. When the plastic packaging injection process is performed on the motor, the plastic packaging material flows into the groove to fill the groove. The plastic packaging material flows from the back channel of the groove to the back of the front and back barriers to cover the front and back of the front and back barriers. This not only improves the connection strength of the overall structure, but also prevents plastic packaged materials from easily falling off the front and rear barrier components.

절연단부에 걸림홈이 형성되어 있으며, 걸림홈은 고정자 철심의 T자형 돌기부에 결합된다. A locking groove is formed at the insulated end, and the locking groove is coupled to the T-shaped protrusion of the stator iron core.

챔버의 상부측에 위치한 하우징의 계단면 위로 다수의 접선용 시트가 연장 설치되고 그 중 일부 접선용 시트는 코일권선에 연결되므로 편리하게 접선할 수 있다. A plurality of tangential sheets are installed on the stepped surface of the housing located on the upper side of the chamber, and some of the tangential sheets are connected to the coil windings so that they can be conveniently tangled.

챔버의 상부측에 위치한 하우징의 계단면으로부터 제어회로판을 고정하기 위한 다수의 위치고정용 기둥이 연장 설치되어 있어 편리하게 사용할 수 있다. A plurality of position fixing pillars for fixing the control circuit board from the stepped surface of the housing located on the upper side of the chamber are extended and can be conveniently used.
