Description
본 발명은 스위치드릴럭턴스 전동기에 관한 것으로서, 특히 전동기의 장시간 운전시 센서디스크상에 먼지가 쌓여 위치검출센서의 동작불능이 발생하지 않도록 효과적으로 먼지를 제거하기위한 방진형 센서디스크구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch drill lux motor, and more particularly, to an anti-vibration type sensor disk structure for effectively removing dust so that dust does not accumulate on the sensor disk during long time operation of the motor, thereby preventing malfunction of the position detection sensor.
종래 스위치드릴럭턴스 전동기구조를 살펴보면 도 1에서와 같이 전동기의 부싱(1)에는 원통형가이드(2)가 설치되고, 상기 부싱(1)에 형성된 돌기(5)에는 센서디스크(4)가 회전자축(3)과 함께 회전되도록 결합되었다.Referring to the structure of the conventional switch drill lux motor, the cylindrical guide 2 is installed in the bushing 1 of the motor as shown in FIG. 1, and the sensor disk 4 is formed on the protrusion 5 formed on the bushing 1. Combined to rotate with (3).
도면중 미설명 부호 7은 구동회로이며, 6과 8은 각각 틈새를 나타낸다.In the figure, reference numeral 7 denotes a driving circuit, and 6 and 8 denote gaps, respectively.
이와같이 구성되는 종래 구성에서 센서디스크(4)는 도 2에서 보인 4개소의 회전자극(11)에 맞추어 도 3에서 보는바와 같은 형상으로 4개소의 센싱위치(11)와 회전자축에 삽입하기 위해 중심부에 구멍(12)을 형성하였다.In the conventional configuration configured as described above, the sensor disk 4 has a central portion for insertion into the four sensing positions 11 and the rotor shaft in the shape as shown in FIG. 3 in accordance with the four rotational stimuli 11 shown in FIG. 2. Holes 12 were formed in the holes.
그러나 디스크에 유입되는 먼지를 저감하는 역할을 하는 원통가이드(2)와 센서디스크(4) 사이에는 메카니즘적인 작동을 위해서 어느정도의 틈새(6)를 두어야만 하므로, 여기로 침투하는 먼지가 장기간에 걸쳐 센서디스크(4)에 쌓일수가 있고, 센서가 위치하는 구동회로(7) 역시 주위틈새(8)로 인해 전동기 동작불능이 일어나게되는 문제점이 있었다.However, some clearance (6) must be provided between the cylindrical guide (2) and the sensor disk (4), which serves to reduce the dust flowing into the disk, for the mechanism to operate. There is a problem that can be stacked on the sensor disk 4, the drive circuit 7 in which the sensor is located also causes the motor inoperable due to the peripheral gap (8).
본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로서, 센서디스크에는 중심부구멍으로 부터 토출되는 공기를 안내하여 디스크상의 먼지쌓임을 방지하도록 디스크상에 다수개의 송풍안내깃을 형성함으로서, 센서디스크상에 쌓이는 먼지를 능동적으로 제거하는데 목적이 있다.The present invention is invented to solve the problems of the prior art as described above, by forming a plurality of blowing guide feathers on the disk to guide the air discharged from the central hole in the sensor disk to prevent dust accumulation on the disk It aims to actively remove dust accumulated on the sensor disk.

본 발명을 도 4를 참조하여 이하에서 상세히 설명한다.The present invention is described in detail below with reference to FIG.
먼저 본 발명 센서디스크의 구조를 살펴보면 회전자극 4개소의 대응하는 4개소의 센싱위치(101)와 회전자축에 삽입하기 위한 중심부구멍(102)을 형성하는 것은 종래와 동일하지만, 중심부구멍(102)을 중심으로 방사방향으로 다수개의 송풍안내깃(103)을 형성하였다.First, referring to the structure of the sensor disk of the present invention, the center hole 102 for inserting into the corresponding four sensing positions 101 of the four rotary stimuli and the rotor shaft is the same as the conventional one, but the central hole 102 is formed. A plurality of air blowing guide feathers 103 were formed in the radial direction.
이와같이 구성된 상태에서 전동기가 동작하여 디스크가 회전하게 되면 본 발명의 송충안내깃(103)에 의해 입구부(A)에서 부터 출구부(B) 방향으로 압축된 고속의 공기를 밀어내므로 출구부(B) 선단에 형성된 센싱위치(101)상의 먼지를 제거할 수 있는 것이다.When the disk is rotated by operating the electric motor in the state configured as described above, the high speed air compressed from the inlet portion A toward the outlet portion B by the feeding guide blade 103 of the present invention is the outlet portion ( B) it is possible to remove the dust on the sensing position 101 formed at the tip.
또한 송풍안내깃(103)은 도 4의 (b)의 나타낸 단면도와 같이 별도의 재료를 부착하지 않고 금형제작에 의해 안내깃을 세우게 됨으로 재료비 증가의 문제점도 방지하게 된다.In addition, the blowing guide feather 103 is to prevent the problem of increasing the material cost by standing the guide feather by the mold production without attaching a separate material as shown in the cross-sectional view of Figure 4 (b).
이상 설명한 바와같이 본 발명의 센서디스크구조는 원통형 가이드를 설치하지 않고서 전동기의 회전력만을 이용하여 센서디스크상의 먼지를 제거함으로, 원통형 가이드 추가에 따른 재료비증가와, 조립에 따르는 생산성저하등의 문제점을 해결할 수 있는 효과가 있다.As described above, the sensor disk structure of the present invention eliminates dust on the sensor disk using only the rotational force of the motor without installing the cylindrical guide, thereby solving problems such as material cost increase due to the addition of the cylindrical guide and reduced productivity due to assembly. It can be effective.
