摘要

在本研究中，我们开发和研究了一种主要用于感应电机的新型无取向电工钢(50H-CP)。该材料具有高通量密度和低铁损耗的特点。我们通过制造一个测试电机，并将其性能与另一个使用标准材料(50H350)的电机进行比较，确认了新材料的效果。50H-CP电机的效率比50H350电机的效率提高了1%，因为前者的铜损耗低。此外，利用电磁场分析对电机损耗的击穿进行了评估。铁损失在50H-CP和50H350之间具有可比性。然而，50H-CP在一次和二次铜损失方面优于50H-CP。以上结果从理论上证实了50H-CP高磁通密度-低铁损特性的影响。

EFFECT OF A NEW NON-ORIENTED ELECTRICAL STEEL SHEET WITH HIGH MAGNETIC FLUX DENSITY AND LOW IRON LOSS ON INDUCTION MOTOR PERFORMANCE

In this study, we developed and investigated a new non-oriented electrical steel (50H-CP) to be used in mainly induction motors. This material exhibits high flux density and low iron loss. We confirmed the effect of the new material by manufacturing a test motor and comparing its performance against another motor with a standard material (50H350). The efficiency of the motor with 50H-CP showed an improvement of 1% compared to the one with 50H350 because of the low copper losses in the former. Furthermore, the breakdown of the motor losses was evaluated using electromagnetic field analysis. The iron loss was comparable between 50H-CP and 50H350. However, 50H-CP was superior with regard to primary and secondary copper losses. From the above results, the effect of the high magnetic flux density-low iron loss characteristics of 50H-CP was theoretically confirmed.
