发布时间：2018-09-08 06:08
【摘要】：高效、超高效电动机的设计关键是降低各项损耗。然而,无论是使用高质量的电工钢材料还是改进电机结构降低铁耗都离不开对电工钢材料复杂磁特性的准确把握。为深入研究实际工况下电工钢片损耗特性,利用先进的电工钢片旋转磁特性测量装置,研究了无取向电工钢片单位铁损特性及其与磁化方式、磁化轨迹的关系。从提高旋转损耗计算精度和工程实用性角度,提出了修正的椭圆损耗计算模型和修正的正交分解损耗模型,验证了修正模型对近乎实际工况下铁损计算的有效性。研究表明,修正的损耗计算模型降低了实施矢量磁滞模型与有限元耦合计算旋转铁耗的复杂程度,满足了工程精度要求。由于修正模型的系数充分拟合了旋转特性测量数据,所以降低了模型应用过程中对旋转磁特性测量装置的依赖,提高了模型的实用性。
[Abstract]:The key to the design of high-efficiency and super-efficient motor is to reduce the loss. However, the use of high quality electrical steel materials or the improvement of motor structure to reduce iron loss are inseparable from the accurate grasp of the complex magnetic properties of electrical steel materials. In order to study the loss characteristics of electrical steel sheet under actual working conditions, the characteristics of unit iron loss of non-oriented electric steel sheet and its relationship with magnetization mode and magnetization track are studied by using advanced rotating magnetic characteristics measuring device of electric steel sheet. A modified elliptical loss model and a modified orthogonal decomposition loss model are proposed in order to improve the accuracy of rotary loss calculation and the engineering practicability. The validity of the modified model for the calculation of iron loss under near actual working conditions is verified. The results show that the modified loss calculation model reduces the complexity of applying the vector hysteresis model and the finite element coupling to calculate the rotary iron loss, and meets the requirement of engineering precision. Because the coefficients of the modified model fully fit the measured data of the rotational characteristics, the dependence of the model on the rotating magnetic characteristic measurement device is reduced, and the practicability of the model is improved.
