Abstract

본 발명은 브러시리스모터의 과전류제어방법에 관한 것으로, 종래에는 과전류제어회로를 하드웨어로 구성함으로써 회로정수계산 및 부품선정에 따른 신뢰성 저하로 과전류 유입시 부품이 파괴되거나 각 회로의 지연시간에 의해 과전류를 감지못하는 문제점이 있었다.The present invention relates to an overcurrent control method of a brushless motor, and in the related art, the overcurrent control circuit is composed of hardware, which causes parts to be destroyed when an overcurrent flows due to a decrease in reliability according to circuit constant calculation and component selection, or an overcurrent due to a delay time of each circuit. There was a problem not detecting.

이러한 점을 감안하여 본 발명에서는 하드웨어 구성을 줄임과 아울러 검출한 과전류 상태를 프로그램에 의해 분류 처리함으로써 과전류 유입시 대응 동작이 빠르고 순간적인 과전류에 의한 모터의 동작정지를 방지하여 신뢰성을 향상시킬 수 있다.In view of this, in the present invention, by reducing the hardware configuration and classifying the detected overcurrent state by a program, it is possible to improve the reliability by preventing the operation of the motor due to rapid and instantaneous overcurrent when the overcurrent flows. .
