本文检验了安装于马达铁芯中的NC-MI和NC～BI高效铁芯材料的磁性及有关性能,此铁芯用于改进过的感应型马达。当使用这类新材料时,马达的效率更高,这主要归于它的低铁损。本文认为获得马达低铁损的原因是由于这类钢材使用在设定的磁感应强度情况下时较低的交流铁损,和在设定磁感应强度以外时的较低的转动铁损以及高频情况时较低的铁损。鉴于高效铁芯材料其已改善了的晶体织构和较小的晶粒尺寸,从而能满足得到较低交流铁损、较低转动铁损以及高频时的低铁损要求。 1、前言为了改进常规通用薄片磁性材料(C、R、M、Q)的磁性,发展了具有高磁导率、低铁损的高效铁芯材料-“新铁芯NC-MI和:NC-BI”。对于NC-MI和NC～BI,因分别提高了(100)<0VW>和(1mo)<001>晶粒织构,所以有较好的磁化特性,
This article examines the magnetic and related properties of NC-MI and NC ~ BI high-efficiency core materials mounted in a motor core that is used to retrofit an induction-type motor. When using this new material, the motor is more efficient, thanks in large part to its low iron loss. This paper argues that the reason for the low iron loss of the motor is due to the low ac losses of the steels used at the set magnetic flux density and the low rotational loss of iron at the time of setting the magnetic flux density and the high frequency Lower iron loss. In view of the improved crystal texture and the smaller grain size of the highly efficient core material, it is possible to meet the requirements of obtaining lower ac losses, lower revolving core losses, and lower losses at high frequencies. 1. INTRODUCTION In order to improve the magnetic properties of conventional general-purpose lamellar magnetic materials (C, R, M, Q), an efficient core material with high magnetic permeability and low iron loss has been developed - “New Core NC-MI and: NC- BI ”. For NC-MI and NC ~ BI, the magnetization characteristics are better because the (100) <0VW> and (1mo) <001>
