초록
본 논문은 ADC 컨버터 내장 단상 직입구동 20W BLDC 모터 개발 및 출력 특성에 대한 연구결과를 논하였다. PWM 인버터 스위칭을 통해 회전자를 구동시키고, 모터의 역기전력을 홀센서 위상각 신호보다 전기적으로 30° 앞서도록 위치시켜 최적의 스위칭 타임을 확보하도록 제작하였다. 특성평가의 주요한 결과로서 인버터 효율 최대 92[%], 시스템 효율 53.34[%]를 보였으며, 모터 효율은 57.85[%] 보였다.
Abstract
This paper discussed the research results on the development and output characteristics of single-phase direct drive20W BLDC motor with ADC converter. It is designed to drive the rotor through PWM inverter switching and positionthe back electromotive force of the motor electrically 30° ahead of the hall sensor phase angle signal to ensureoptimum switching time. As a major result of the characteristics evaluation, the maximum inverter efficiency was92[%], the system efficiency was 53.34[%,] and the motor efficiency was 57.85[%].
