在汽车上为了提高安全性和舒适性而使用着各种类型的马达 ,一辆汽车往往要使用几十台马达。影响马达效率的首先是所用的铁芯材料 ,作为铁芯材料用硅钢的最佳Ｓｉ含量 ,则随马达转速和设计磁通密度而有所不同。近年来为了满足对低铁损和高磁导率等日益刻苛的要求 ,在制造电工硅
Various types of motors are used in automobiles to improve safety and comfort, and dozens of motors are often used in one automobile. The most important factor influencing motor efficiency is the core material used. The optimum Si content for the silicon steel used as the core material varies with the motor speed and the design flux density. In recent years in order to meet the increasingly low iron loss and high permeability and other increasingly demanding requirements in the manufacture of electrical silicon
