Abstract

브러시에 함유되는 동분말의 함량을 증대시킴이 없이 전동기의 출력 특성을 향상시킬 수 있을 뿐만 아니라 소음 특성 및 내마모 특성을 향상시키기 위하여 본 발명은 섬유 입자상의 동분말을 첨가시켜서 브러시를 제작하는 방법을 제공한다.In order to improve the output characteristics of the motor without increasing the content of the copper powder contained in the brush, as well as to improve the noise characteristics and abrasion resistance, the present invention provides a method of manufacturing a brush by adding copper powder on fiber particles. To provide.
