电工钢片旋转损耗特性分析与损耗模型修正
Analysis of Rotational Loss Property in an Electrical Steel Sheet and Correction of Loss Model
摘要
Abstract
The key for designing a high-efficiency or super high-efficiency motor is to decrease the various losses. However, whether the high-quality electrical steel is employed or the structure of electrical motor is improved to degrade the loss, it will be greatly dependent on deep understandings of the complicated magnetic property of electrical steel. In order to study the loss property of electrical steel material under the actual working conditions deeply, the specific loss of non-oriented electrical steel and its relation with the magnetization patterns and magnetization loci were investigated by using an advanced measurement system of rotational magnetic property. From the viewpoint of high accuracy of loss computation and strong engineering application, the corrected elliptical loss model and orthogonal decomposition loss model were proposed, respectively and their validity of calculating the iron loss under almost actual working conditions was verified. The studies show that the corrected model has the advantages, such as reducing the complex course of rotational loss computation by coupling the vector magnetic hysteresis model and finite element formula, and satisfying the accuracy of engineering application. Since the coefficients in the corrected model are obtained by fitting the measured data about rotational property, the dependence of loss model in the application on the measurement system of rotational property is reduced and the practical value is strengthened.关键词
