본 고안은 모터의 회전자 절연체에 관한 것으로서, 모터의 회전자의 형태에 부합되도록 구성되어 회전자 양측단으로 삽입결합시킴으로써, 모터의 회전자에 권선되는 코일로부터 절연기능을 향상시킴은 물론 조립이 용이하고 안전성이 뛰어난 모터의 회전자 절연체에 관한 것이다.The present invention relates to a rotor insulator of a motor, which is configured to match the shape of a rotor of the motor and is inserted into and coupled to both ends of the rotor, thereby improving the insulation function from the coil wound on the rotor of the motor as well as assembling. It relates to a rotor insulator of a motor which is easy and excellent in safety.

일반적으로 대부분의 모터는 전류인가에 따른 회전자가 구비되어 있는데, 회전자는 코일이 권선 되어 구성되며, 전류가 인가되면 회전자에 자력이 발생되어 극성이 형성하게 된다.In general, most motors are equipped with a rotor according to the application of the current, the rotor is configured by winding the coil, when the current is applied to the magnetic force is generated to form a polarity of the rotor.

이러한 회전자는 중앙으로 회전축이 삽입되며 회전자에 형성된 홈에 대해 절연물질을 코팅처리하여 사용하였다.The rotor is inserted into the center of the rotation axis was used to coat the insulating material for the groove formed in the rotor.

이러한, 구성의 회전자는 결함 발생시 절연물이 코팅된 회전자 전체를 폐기해야하므로 제조 단가가 상승하는 문제점이 발생하고, 절연물의 코팅시에 불균일하게 증착될 경우 회전자의 회전에 영향을 미쳐 진동 및 소음을 유발할 뿐만 아니라 수명을 단축시키게 되는 문제점이 발생하였다.This, the rotor of the configuration has a problem that the manufacturing cost rises because the entire rotor is coated with insulation when a defect occurs, and if unevenly deposited during coating of the insulation affects the rotation of the rotor vibration and noise In addition to causing the problem that shortens the life has occurred.

또 다른 구성으로 회전자에 코일이 권선되는 홈에 대해서 상기 홈의 간견과 크기에 부합되는 크기의 절연체를 구성하여 회전자에 삽입함으로써 절연기능을 수행하는 방법이 제시되어 사용되고 있다.In another configuration, a method of performing an insulation function by forming an insulator having a size corresponding to the groove and size of the groove and inserting it into the rotor with respect to the groove on which the coil is wound is used.

그러나 상기와 같은 방법의 경우 회전자의 코일이 권선되는 홈의 내측으로는 절연기능이 가능하나, 코일이 권선 되고 난 후 그 외측은 그대로 뚫려있는 공간으로 남아있어, 확실한 절연의 기능을 할 수 없는 단점이 있었다.However, in the above method, insulation function is possible inside the groove in which the coil of the rotor is wound, but after the coil is wound, the outside remains as a perforated space, and thus cannot function as a reliable insulation.
