초록

최근 가전제품에 브러시리스 직류 (Brushless DC) 전동기의 센서리스 드라이브를 적용시키는 사례가 증가하고 있다. 특히 사람들의 삶의 질이 향상 됨에 따라 가정에서 가장 밀접하게 연관되어 있는 냉장고, 에어컨과 같은 가전제품에 가청소음을 줄여 보다 편안하고 안락한 생활을 추구하고 있다. 본 논문에서는 브러시리스 직류전동기에 랜덤 PWM을 적용한 냉장고용 압축기의 저가형 센서리스 드라이브를 이용하여 기존 드라이브 보다 가격과 소음을 줄일 수 있음을 실험하였다. 이러한 실험으로 전자적 소음을 줄임으로써 소음에 질을 향상시킬 수 있음을 확인할 수 있었다.

Recently, it is increased to apply sensorless drive for BLDC (Brushless DC) motor to household electrical appliances, especially in the refrigerators and air conditioners, to reduce the cost and the acoustic noise by the operation and to make their functions more comfortable for human beings. In this paper, low-cost sensorless drive for BLDE motor is implemented by random PWM (Pulse Width Modulation). The experimental results show that the electromagnetic noise was reduced and the sound quality was improved by BLDC motor sensorless random PWM Control.
