Description

에스.알.엠 제어용 센서 및 센서회로기판의 취부구조{Mounting structure of sensor and sensor PCB for controlling SRM}Mounting structure of sensor and sensor PCB for controlling SRM

본 발명은 SRM에 관한 것으로서, 보다 상세하게는 회전자의 위치정보 검출을 위한 SRM 제어용 센서 및 센서회로기판의 취부구조에 관한 것이다.The present invention relates to an SRM, and more particularly, to a mounting structure of an SRM control sensor and a sensor circuit board for detecting position information of a rotor.

일반적으로 SRM(switched reluctance motor)은 회전자에 권선이나 영구자석이 없는 구조로 이루어지고, 구동회로가 간단하여 제작비용이 저렴하고, 회전자의 관성이 적으며 넓은 범위의 속도에서 고효율운전이 가능하기 때문에 그 구조 및 작동상 여러 이점을 갖는 전동기이다.In general, the switched reluctance motor (SRM) is made of a structure without windings or permanent magnets in the rotor, and the driving circuit is simple, so the manufacturing cost is low, the inertia of the rotor is low, and high efficiency operation is possible at a wide range of speeds. Therefore, the motor has various advantages in structure and operation.

한편, 이와 같은 SRM의 속도제어를 위해서는 회전자의 위치각에 대한 정보가 필수적이므로 위치 정보를 검출하기 위한 센싱수단을 필요로 하는데, 상기 센싱수단은 도 1에 나타난 것과 같이 센서회로기판(10)과 상기 센서회로기판(10)에 부착된 센서(12)로 이루어져 있다.On the other hand, since the information on the position angle of the rotor is essential for the speed control of the SRM, a sensing means for detecting the position information is required, and the sensing means is a sensor circuit board 10 as shown in FIG. And a sensor 12 attached to the sensor circuit board 10.

상기 센서회로기판(10)은 SRM의 전면측에 장착된 프런트 하우징(20)을 통해 장착되는데, 상기 프런트 하우징(20)은 그 가장자리에 테두리부(201)가 형성되고, 중앙에 회전축(미도시)의 돌출을 위한 관통홀(20a)이 형성된 구조로 이루어져 있으며, 상기 센서회로기판(10)은 대략 평판형의 구조로서 센서(12)의 위치가 회전자(미도시)의 회전반경 내에 위치되도록 프런트 하우징(20)의 일측면에 부착된다.The sensor circuit board 10 is mounted through the front housing 20 mounted on the front side of the SRM, the front housing 20 is formed with an edge 201 at the edge thereof, the axis of rotation (not shown) The through-hole 20a for protruding the structure is formed, and the sensor circuit board 10 has a substantially flat structure so that the position of the sensor 12 is located within a rotation radius of the rotor (not shown). It is attached to one side of the front housing 20.

따라서, 상술한 바와 같은 종래기술에 의하면 회전자의 회전방향과 직교하도록 프런트 하우징(20)에 장착된 센서(12)의 위치상 회전자의 위치정보를 검출하게 되는 것이다.Therefore, according to the related art as described above, the position information of the rotor is detected on the position of the sensor 12 mounted on the front housing 20 so as to be orthogonal to the rotation direction of the rotor.

그러나, 이러한 종래기술에 의하면 센서회로기판(10)의 취부 시 그 구조적인 특성(단순한 평판형)에 의해 프런트 하우징(20)에 견고하게 형합되지 않기 때문에 상하 또는 좌우로 취부오차가 발생하고, 센서(12)의 위치 또한 변동되는 등, 결과적으로 회전자의 위치정보가 정밀하게 검출되지 않아 SRM의 작동 안정성이 저하된다는 문제가 발생한다.However, according to this conventional technology, when mounting the sensor circuit board 10, the mounting characteristic is generated up and down or left and right because the structural characteristics (simple flat type) are not firmly matched to the front housing 20. The position of (12) also changes, and as a result, a problem arises that the positional information of the rotor is not detected precisely and the operation stability of the SRM is lowered.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로서, 센서 및 센서회로기판의 고정상태가 더욱 견고해짐으로써 SRM의 작동 안정성 향상에 도움이 되는 SRM 제어용 센서 및 센서회로기판의 취부구조 제공을 목적으로 한다.The present invention has been made to solve the above-mentioned problems, and the object is to provide a mounting structure of the sensor and the sensor circuit board for controlling the SRM to help improve the operational stability of the SRM by more secure the fixed state of the sensor and the sensor circuit board. do.

상기 목적을 달성하기 위하여 제공되는 SRM 제어용 센서 및 센서회로기판의 취부구조는 상기 센서회로기판이 프런트 하우징의 테두리부와 밀착됨으로써 그 부착상태가 견고하게 유지되도록 하는 몰딩물에 의해 취부되고, 센서 역시 센서회로기판과의 접합상태가 견고하게 유지되도록 하는 몰딩물에 의해 상기 센서회로기판에 접합된 것을 특징으로 하여 이루어진다.The mounting structure of the SRM control sensor and the sensor circuit board provided to achieve the above object is mounted by a molding that the sensor circuit board is in close contact with the edge of the front housing so that its attachment state is firmly maintained, It is characterized in that it is bonded to the sensor circuit board by a molding to keep the bonding state with the sensor circuit board firmly.

이하, 본 발명의 실시예를 첨부된 도 2와 도 3을 참조로 하여 상세하게 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 and 3.

우선, 본 발명의 실시예에 따른 SRM 제어용 센서 및 센서회로기판의 취부구조는 도 2에 나타난 것과 같이 센서회로기판(11)이, 프런트 하우징(20)의 테두리부(201)와 밀착되는 형태로 이루어지고 그 부착상태가 견고하게 유지되도록 하는 이른바 베이스 몰딩물(30)에 의해 취부된다.First, the mounting structure of the SRM control sensor and the sensor circuit board according to an embodiment of the present invention is such that the sensor circuit board 11 is in close contact with the edge portion 201 of the front housing 20, as shown in FIG. Is made by the so-called base moldings 30 which are made and which keep their attachment firm.

그리고, 도 3에 나타난 것과 같이 센서(12) 역시 센서회로기판(11)과의 접합상태가 견고하게 유지되도록 하는 이른바 커버 몰딩물(32)에 의해 상기 센서회로기판(11)에 접합된다.As shown in FIG. 3, the sensor 12 is also bonded to the sensor circuit board 11 by a so-called cover molding 32 to maintain the bonding state with the sensor circuit board 11.

여기서, 상기 각 몰딩물(30)(32)은 합성수지 등의 재질로 이루어지는데, 커버 몰딩물(32)의 경우에는 센서(12) 높이의 약 2/3 정도의 두께로 구성되며, 센서회로기판(11)의 표면과 일치하는 형태로 이루어진다.Here, each of the moldings 30, 32 is made of a material such as synthetic resin, in the case of the cover molding 32 is composed of a thickness of about 2/3 of the height of the sensor 12, the sensor circuit board It is made in the form coinciding with the surface of (11).

베이스 몰딩물(30)은 프런트 하우징(20)의 테두리부(201) 사이에 끼움장착 가능한 정도의 폭과 두께로 이루어지는데, 특히 프런트 하우징(20)의 완만한 곡률형상과 일치되는 형태로 이루어진다.The base molding 30 has a width and a thickness that can be fitted between the edge portions 201 of the front housing 20, and in particular, the base molding 30 has a shape that matches the gentle curvature of the front housing 20.

이에 따라, 상술한 바와 같은 본 발명의 실시예에 의하면, 커버 몰딩물(32)에 의해 센서(12)의 취부상태가 견고해지며, 베이스 몰딩물(30)에 의해 센서회로기판(11)의 취부상태 역시 견고해진다.Accordingly, according to the embodiment of the present invention as described above, the mounting state of the sensor 12 is firm by the cover molding 32, and the base of the sensor circuit board 11 by the molding 30 The mounting condition is also firm.

더욱이, 상기 베이스 몰딩물(30)은 그 구조적인 특성상 프런트 하우징(20)과 형합되기 때문에 센서회로기판(11)의 취부상태를 견고하게 유지토록 할 뿐만 아니라, 취부작업 시 베이스 몰딩물(30)이 부착된 상태의 센서회로기판(11)을 프런트 하우징(20)에 밀어 넣는 단순한 작업만으로도 센서회로기판(11)이 정확한 위치에 안착되도록 함으로써 취부작업의 효율 또한 향상된다.Furthermore, since the base molding 30 is combined with the front housing 20 due to its structural characteristics, the base molding 30 not only maintains the mounting state of the sensor circuit board 11 firmly, but also the base molding 30 during the mounting operation. The efficiency of the attaching operation is also improved by allowing the sensor circuit board 11 to be seated in the correct position by simply pushing the sensor circuit board 11 in the attached state into the front housing 20.

본 발명에 따른 SRM 제어용 센서의 취부구조에 의하면, 센서 및 센서회로기판의 고정상태가 몰딩물을 통해 더욱 견고해짐으로써 회전자의 위치정보가 정밀하게 측정되는 등, SRM의 작동 안정성 향상에 도움이 된다.According to the mounting structure of the sensor for controlling the SRM according to the present invention, the fixed state of the sensor and the sensor circuit board is further strengthened through the molding, which helps to improve the operation stability of the SRM, such as precisely measuring the position information of the rotor. do.
