在评估电机和三相变压器的铁损时，应考虑旋转铁损。提出了一种计算高磁通密度不同轴比旋转磁通下旋转铁损的简单数值计算方法。结果表明，将旋转磁通分解为旋转磁通的长轴方向和短轴方向是计算低磁化区无取向和取向电工钢板旋转铁损的有效方法。然后，对简单的铁损计算方法进行了改进，以考虑圆形旋转磁通作用下高磁化区旋转磁滞和反常涡流损耗的减小，并与测量结果进行了对比验证。并对其进行了改进，使其适用于不同轴比旋转磁通下的旋转铁损计算，并与测量结果进行了对比验证。
To evaluate the iron losses of motors and three-phase transformers, the rotational iron loss should be considered. A simple numerical calculation method of the rotational iron losses under rotational flux with high flux density and different axis ratios is proposed in this paper. First, it is shown that the method of decomposing the rotational flux into the directions of the major and minor axes of the rotational flux is effective in calculating the rotational iron losses of the non-oriented and grain-oriented electrical steel sheets in low magnetization region. Then, the simple iron loss calculation method is improved to consider the decrease of rotational hysteresis and anomalous eddy current losses in high magnetization region under circular rotational flux and verified by comparing with measurement results. Furthermore, it is improved to be applicable to rotational iron loss calculation under rotational flux with different axis ratios and verified by comparing with measurement results.
