* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 스핀들 2 : 코어1: spindle 2: core

3 : 캡 3a : 슬롯 웨지3: cap 3a: slot wedge

3b : 곡면부3b: curved part

본 고안은 정류자 전동기용 슬롯 웨지(Slot Wedge)에 관한 것으로, 특히 전기자의 조립시 슬롯 웨지를 한동작으로 삽입시킬 수 있도록 캡과 일체로 형성하여 전기자의 조립이 용이하도록 한 것이다.The present invention relates to a slot wedge for a commutator electric motor, and in particular, is formed integrally with the cap so that the slot wedge can be inserted in one operation when assembling the armature to facilitate the assembly of the armature.

일반적으로 모터의 운전시 팬에 의해 공기를 모터측으로 흡입하는 정류자 전동기는 제 1 도와 같이 팬(7)에 고정된 스핀들(1)에 정류자(4)를 고정함과 함께 정류자(4)의 일측에 카본 브러쉬(Carbon Brush)(8)를 설치하고 그 하방에는 슬롯 웨지(9)로 코어(2)로 고정하도록 되어 있다.In general, a commutator electric motor that sucks air to the motor side by a fan during operation of the motor, while fixing the commutator 4 to the spindle 1 fixed to the fan 7 as the first diagram, is connected to one side of the commutator 4. A carbon brush 8 is provided and fixed to the core 2 by a slot wedge 9 below.

그러나 종래에는 스핀들(1)의 회전시 코어(2)의 이탈을 방지하기 위한 슬롯 웨지(9)를 코어(2)의 슬롯수만큼 제작하여 코어(2)에 일일이 삽입 고정하였기 때문에 작업능률이 저하되었을 뿐 아니라 코일(5)이 외부로 노출된 상태로 되어 있어 스핀들(1)이 회전하면 정류자(4)와 카본 브러쉬(8) 사이에 마찰이 발생하여 카본 가루가 코일(5)에 묻게되고, 계속해서 스핀들(1)이 회전함에 따라 코일(5)에 많은 양의 카본 가루가 쌓이게 되면 코일(5)과 코어(2)사이가 연결되어 쇼트의 원인이 되며, 또한 스핀들(1)의 고속회전이 정류자핀(10)과 접속된 코일(5)이 공기와 마찰음을 발생시켜 전동기의 소음을 증가시키게 되는 결점이 있었다.However, in the related art, since the slot wedge 9 for preventing the detachment of the core 2 when the spindle 1 rotates is manufactured by the number of slots of the core 2 and inserted into the core 2, the work efficiency decreases. In addition, the coil 5 is exposed to the outside, and when the spindle 1 rotates, friction occurs between the commutator 4 and the carbon brush 8, and carbon powder is buried in the coil 5, As the spindle 1 rotates continuously, when a large amount of carbon powder accumulates in the coil 5, the coil 5 and the core 2 are connected to each other, causing a short circuit, and the spindle 1 rotates at a high speed. The coil 5 connected to the commutator pin 10 generates a frictional noise with air, thereby increasing the noise of the electric motor.

본 고안은 종래의 이와같은 결점을 감안하여 안출한 것으로 코어의 이탈을 방지하기 위한 슬롯 웨지를 곡면부를 가지는 캡과 일체로 형성한 것인바, 이를 첨부된 도면 제 2 도 내지 제 3 도에 의해 더욱 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-described drawbacks of the prior art, the slot wedge for preventing the departure of the core is formed integrally with the cap having a curved portion, which is further by the accompanying drawings 2 to 3 It will be described in detail as follows.

스핀들(1)의 회전시 코어(2)의 이탈을 방지하기 위해 삽입하는 슬롯 웨지에 있어서, 다수개의 슬롯 웨지(3a)를 캡(3)의 하방에 일체로 형성하고 그 상방에는 곡면부(3b)를 형성하여서 된 것으로 도면중 미설명 부호 6은 절연물이다.In the slot wedge inserted to prevent separation of the core 2 when the spindle 1 rotates, a plurality of slot wedges 3a are integrally formed under the cap 3, and the curved portion 3b thereon. In Fig. 6, reference numeral 6 denotes an insulator.

이와같이 구성된 본 고안은 하방에 다수개의 슬롯 웨지(3a)가 형성된 캡(3)을 스핀들(1)의 상방을 통해 코어(2)의 슬롯에 삽입하면 운전시 발생되는 카본 가루가 캡(3)의 상방에 형성된 곡면부(3b)를 통해 하방으로 떨어지게 되므로 코일(5)을 카본 가루로 부터 보호하여 코일(5)의 쇼트로 인한 기기의 파손을 미연에 방지할 수 있고 스핀들(1)의 고속회전시에도 코일(5)과 공기의 마찰저항이 최소화되어 전동기의 소음을 줄일 수 있게 되며, 또한 슬롯 웨지(3a)가 형성된 캡(3)을 스핀들(1)의 상방을 통해 코어(2)의 슬롯에 삽입하여 주기만 하면 코어(2)가 고정되므로 코어(2)의 슬롯에 슬롯 웨지를 일일이 삽입하여 주던 종래의 것에 비해, 작업 능률을 향상시킬 수 있는 효과가 있다.According to the present invention configured as described above, when the cap 3 having the plurality of slot wedges 3a formed therein is inserted into the slot of the core 2 through the spindle 1, the carbon powder generated during the operation of the cap 3 Since it falls downward through the curved portion 3b formed above, the coil 5 can be protected from carbon powder to prevent damage to the device due to the short of the coil 5 and the high speed rotation of the spindle 1 When the frictional resistance between the coil 5 and the air is minimized, the noise of the electric motor can be reduced, and the cap 3 having the slot wedge 3a is formed in the slot of the core 2 through the spindle 1. Since the core 2 is fixed only by inserting it into the slot, the work efficiency can be improved as compared with the conventional inserting the slot wedge into the slot of the core 2.
