본 고안은 코어를 적충하여 전기자 권선에 많은 계자 자속을 쇄교하는 회전기기에 있어서, 코어의 슬롯트 사이에서 발생되는 코깅(Cogging)력을 저하시킬수 있도록 한 회전기기의 코어장치에 관한 것이다.The present invention relates to a core device of a rotating device in which a cogging force generated between slots of the core can be reduced in a rotating device in which a core is loaded to tie many field fluxes to the armature winding.
종래에는 전기자 권선이 감기지는 코어를 형성함에 있어서, 코어에 일정한 상의 슬롯트를 일체로 형성하고 있었으며 이는 코어가 균일한 상태로 일정하게 되어 있기 때문에 영구자석과의 자기 저항변화가 각 슬롯트 사이의 갭에서 집중적으로 발생되고 이에따라 코깅력이 발생되는 회전이 불균형과 더불어 진동등을 유발하게 되었으며 이에따라 회전기기의 성능을 저하시키게 되는 점 등의 문제점이 있었다.Conventionally, in forming a core to which an armature winding is wound, a slot of a certain phase is integrally formed in the core, and since the core is made uniform in a uniform state, the change in magnetoresistance with the permanent magnet is changed between the slots. Rotation generated intensively in the gap and thus cogging force caused an unbalance and vibration, etc. There was a problem such as deteriorating the performance of the rotating device.
본 고안은 상기와 같은 종래의 문제점을 감안하여 코어를 개선하므로서 회전기기에서 발생되는 코깅력을 보다 감소시키고 회전기기의 성능을 증대시킬수 있도록 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made to reduce the cogging force generated in the rotating device and increase the performance of the rotating device by improving the core in view of the conventional problems as described above. same.
영구자석(1)의 내부에 일정한 위상각으로 형성되는 코어(2)를 적층 설치하고 이에 전기자 권선(3)을 설치토록 한 것에 있어서, 코어(2)의 슬롯트(4)에 일정각도와 폭의 요홈부(5)(51)를 여러개 형성하고 요홈부(51)에는 갭(6)을 형성토록 구성하여서 된 것이다.In the case where the cores 2 formed at a constant phase angle are stacked in the permanent magnets 1 and the armature windings 3 are installed thereon, the slots 4 of the cores 2 have a predetermined angle and width. It is to form a plurality of grooves (5) (51) of the grooves and to form a gap (6) in the grooves (51).
이상과 같은 본 고안은 코어(2)의 슬롯트(4)에 일정 각도와 폭으로 요홈부(5)(51)를 형성하고 갭(6)을 형성하므로서 각 슬롯트 사이의 갭에 의해 발생되는 코깅력을 균등하게 분산시키므로서 제2도에서와 같이 감소시킬 수 있으며 이에따라 회전기기의 회전 불균형과 진동을 줄일수 있는 점 등의 특징을 지닌 것이다.The present invention as described above is formed by the gap between each slot by forming the grooves (5) (51) at a predetermined angle and width in the slot (4) of the core (2) and forming the gap (6) By uniformly dispersing the cogging force it can be reduced as shown in Figure 2 and accordingly features such as to reduce the rotational imbalance and vibration of the rotating machine.
