Description

유도전동기용 회전자Rotor for induction motor

제 1 도는 종래 사홈을 가진 회전자.1 is a rotor having a conventional four groove.

제 2 도는 본 고안의형 사홈을 가진 회전자.2 is the present invention Rotor with mold four grooves.

제 3 도는 종래 회전자에 발생되는 힘의 벡터도.3 is a vector diagram of a force generated in a conventional rotor.

제 4 도는 본 고안의 회전자에 발생하는 힘의 벡터도.4 is a vector diagram of the force generated in the rotor of the present invention.

본 고안은 유도 전동기용 회전자의 사홈(skewedslot)을형으로 형성시킨 유도 전동기용 회전자에 관한 것이다.The invention devises the skewslot of the rotor for induction motors. It relates to a rotor for induction motors formed in a mold.

종래에는 제 1 도에 도시한 바와 같이 유도 전동기의 회전자에 사홈을 하는데 있어서 일정한 방향으로 서로 평행하도록 형성하므로써 운전시 고주파의 영향에 의해서 발생되는 전기적인 소음을 제거 시켜 왔다.Conventionally, as shown in FIG. 1, in forming the grooves of the rotor of the induction motor, they are formed to be parallel to each other in a predetermined direction, thereby eliminating the electrical noise generated by the influence of high frequency during operation.

그러나 이러한 방법은 제 3 도의 벡터도에 표현된 바와 같이 회전자의 회전방향과 동일한 방향의 회전 로오크(TQ)와 이것과 90°의 각을 갖는 축방향의 힘(TQS)의 합성력(T)이 발생한다.However, this method has a combined force T of the rotational torque TQ in the same direction as the rotational direction of the rotor and the axial force TQS with an angle of 90 ° as shown in the vector diagram of FIG. This happens.

이때 회전 토오크(TQ)는 실제 운전토오크로 사용되는 힘이며 축방향의 힘(TQS)은 회전자가 고정자로부터 벗어나도록 작용하는 힘으로써 실제로 회전은 합성력에 의해서 운전되므로써 이힘(T)에 의한 자기적인 진동으로 소음을 발생시킴은 물론 베어링의 수명을 단축시키므로서 결과적으로 유도 전동기 자체의 수명을 단축시키는 결점이 있었다.At this time, the rotation torque (TQ) is the force used as the actual operating torque, and the axial force (TQS) is the force acting to move the rotor away from the stator. Actually, the rotation is driven by the synthetic force, and thus the magnetic vibration due to the tooth force (T). As a result of this, the noise generated as well as the life of the bearing are shortened, resulting in shortening the life of the induction motor itself.

본 고안은 이러한 결점을 제거하기 위해서 회전자의 사홈을형으로 형성시킨 것으로 축방향의 힘(TQS)을 서로 상쇄시켜서 전기적인 소음을 완전히 제거시킨 것으로 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention eliminates the grooves of the rotor to eliminate this drawback. Formed in a shape to completely remove the electrical noise by canceling the axial force (TQS) to each other as described in detail by the accompanying drawings as follows.

회전자(1)에 사홈(2)을 형성함에 있어서 회전자(1)의 중앙에서 서로 대칭되게 꺾어서 형상의 사홈(2)을 형성시켜서된 구조로써 미설명 부호 3은 회전축이다.In the formation of the grooves 2 in the rotor 1, a structure formed by forming the grooves 2 of the shape by bending symmetrically with each other in the center of the rotor 1, and reference numeral 3 is a rotation axis.

이와 같은 구조의 본 고안은 운전시에 발생되는 힘의 벡터도는 제 4 도와 같이 회전방향과 동일한 회전토오크(TQ)와 이것과 90°의 각을 가지며 서로 크기가 같고 방향이 정반대인 축방향의 힘인 +TQS와 -TQS가 서로 작용하게되어 실제로는 축방향의 힘(TQS)은 서로 상쇄되어 제거되므로써 종래의 축방향의 힘(TQS)에 의해서 발생되는 자기진동음의 소음이나, 베어링의 수명을 단축시키는 등의 결점을 제거하여 운전시 소음이 전혀 없고 베어링의 수명을 연장시켜 유도 전동기 자체의 수명을 연장시킬 수 있는 특징을 지닌 것이다.According to the present invention of the above structure, the force vector generated during operation has the same rotation torque (TQ) as the rotational direction and the angle of 90 ° with the rotational torque (TQ) as shown in the fourth degree. As the + TQS and -TQS forces act together, the axial force (TQS) cancels each other out and eliminates the noise of the magnetic vibration noise generated by the conventional axial force (TQS), and shortens the life of the bearing. By eliminating the defects such as to make a noise, there is no noise during operation and extends the life of the bearing to extend the life of the induction motor itself.
