Description

전동기 프레임 지지구조Motor frame support structure
본 발명은 전동기 프레임 지지구조에 관한 것으로서, 특히 전동기 프레임의 일측과 타측의 하부 양측이 각각 보강리브에 의하여 지지되도록 함으로써 전체적으로 강성이 보강될 수 있도록 하는 가운데, 공기가 보강리브와 전동기 프레임 사이로 통과되도록 하여 냉각효율을 높임으로써 결과적으로 전동기의 최대 출력을 더 높일 수 있도록 한 것이다.The present invention relates to a motor frame support structure, and in particular, one side of the motor frame and the lower side of the other side is respectively supported by the reinforcing ribs so that the overall rigidity can be reinforced, so that air is passed between the reinforcing ribs and the motor frame. As a result, the cooling efficiency is increased, and as a result, the maximum output of the motor can be further increased.
일반적으로 전동기는 전기 에너지를 기계적인 에너지로 변환시키는 것으로 샤프트, 샤프트에 의하여 지지되어 회전하는 회전자, 회전자와 대향되게 위치하여 고정된 고정자, 고정자를 압입하여 보호 지지하는 프레임으로 구성되어 있다.In general, an electric motor converts electrical energy into mechanical energy, and is composed of a shaft, a rotor supported and rotated by a shaft, a stator positioned opposite to the rotor, and a frame press-fitting and supporting the stator.
전원이 인가됨과 동시에 프레임에 체결 고정된 고정자에 대향되도록 위치된 회전자가 고정자에서 발생되는 자력에 의해 고정자 내측에서 샤프트에 지지된 상태로 고속 회전하여 회전력과 진동이 발생하게 된다. 이때, 회전력에 의한 진동은 프레임이 하부에 구비된 지지다리 즉, 지지구조에 의하여 완화될 수 있게 된다.At the same time as the power is applied, the rotor positioned to face the stator fastened to the frame is rotated at a high speed while being supported on the shaft inside the stator by the magnetic force generated in the stator, thereby generating rotational force and vibration. At this time, the vibration by the rotational force can be alleviated by the support legs, that is, the support structure provided in the lower frame.
또한, 전동기는 내부에서 고속 회전이 반복됨에 따라 고열이 발생하게 되고, 고열을 방치할 경우 출력 저하로 이어지게 되므로 냉각이 이루어지도록 하는 것이 바람직하다.In addition, since the high speed rotation is repeated inside the motor, high heat is generated, and if the high heat is left, it leads to a decrease in output, so that cooling is preferably performed.
도6은 종래 기술에 따른 전동기 프레임 및 지지구조를 도시한 정면도이다.Figure 6 is a front view showing a motor frame and a support structure according to the prior art.
도시된 바와 같이, 전동기 프레임(500)은 외피 표면을 냉각시키기 위한 방안으로 중공형태를 갖는 프레임 몸체(510)의 외주연부에 소정 높이 또는 길이로 돌출된 냉각핀(520)이 방사형태를 갖도록 형성되어 열이 프레임 몸체(510)로 전도되고, 전도된 열이 다시 냉각핀(520)으로 전도되는 과정 중 미도시한 팬에 의하여 공급되는 외기에 의하여 냉각됨에 따라 출력이 저하되는 것을 방지할 수 있게 된다.As shown, the motor frame 500 is formed to have a radial shape of the cooling fin 520 protruding at a predetermined height or length in the outer periphery of the frame body 510 having a hollow shape as a way to cool the outer surface.

그러나 이러한 지지리브(532)는 공기가 통과할 수 없는 구조이어서 전동기가 구동되는 과정중에 국부적으로 냉각이 이루어지지 않는 사각지대가 발생됨에 따라 온도가 불균일해지는 문제점 즉, 국부적으로 과열이 발생되는 문제점이 있었다.However, the support rib 532 is a structure in which air cannot pass, so that a problem occurs in that the temperature is uneven, that is, a local overheating occurs as a blind spot where local cooling is not performed while the electric motor is driven is generated. there was.
또한, 이로 인해 냉각효율이 낮아지게 됨에 따라 출력이 저하되는 문제점과 아울러 고유진동수가 낮아지는 문제점이 있었다.In addition, due to this cooling efficiency is lowered, there is a problem that the output is lowered as well as the natural frequency is lowered.
