摘要

磁力機械如電動機的效率提升一直是產業關注的議題，其中鐵芯損失的功率卻難以直接量測，尤其是在啟動階段或非弦波操作的狀態中，因此許多瞬時鐵損模型在近年仍然被研究討論，特別是對於高頻非弦波操作的小型變壓器。本文比對了兩種由全頻域收斂的瞬時鐵損模型，可以從低頻到高頻及非弦波估算磁力機械的鐵損，並針對中鋼35CS300電磁鋼片牌號比較其相對誤差。

The efficiency improvement of magnetic machinery, such as electric motors, has always been a topic of interest in the industry. However, measuring the power loss in the iron core directly is challenging, especially during startup phases or under non-sinusoidal operating conditions. As a result, many transient iron loss models have continued to be researched and discussed in recent years, particularly for small transformers operating at high frequencies and under non-sinusoidal conditions. This article compares two transient iron loss models that converge across the full frequency spectrum, capable of estimating the iron loss in magnetic machinery from low to high frequencies and under non-sinusoidal waves. It specifically compares the relative errors using the 35CS300 electromagnetic steel grade from China Steel.
