히스테리시스손(Hysteresis Loss)은 변압기나 모터의 철심 같은 자성 재료가 교류 자기장에서 자화·탈자화되는 과정에서, 자기쌍극자의 마찰로 인해 발생하는 에너지 손실(열)입니다.
1. 핵심 특징
발생 원인: 자성 재료 내의 자기구역이 외부 자장 방향으로 재배열되면서 발생하는 내부 마찰.
철손의 일부: 변압기 등에서 발생하는 전체 철손(Iron Loss) 중 하나이며, 와류손(Eddy Current Loss)과 함께 주요 손실 요소임.
2. 히스테리시스손 줄이는 방법
재료 선정: 루프 면적이 작은 연자성 재료(예: 규소강판) 사용.
구조 개선: 규소 함량을 높여 고유 저항을 증대시켜 손실 감소.
3. 영향 및 제어
비효율: 모터나 변압기의 에너지 효율을 낮추고 온도를 상승시킴.
응용: 철심의 자화 특성을 최적화하여 손실을 최소화하는 것이 기기 설계의 핵심.
