摘要 电机定子轭部及齿根部存在大量的椭圆形旋转磁通,其产生的旋转损耗大于交变损耗,因此旋转损耗的准确计算是电机优化设计的前提和基础。该文基于德国RPT型二维旋转磁特性测量系统,测量并分析了无取向电工钢片旋转损耗特性。在研究传统Bertotti损耗三项式模型和斯坦梅兹方程计算铁耗方法的基础上,提出考虑椭圆形旋转磁化下铁心损耗改进模型,并用自制的B-H矢量传感器对一台感应电机定子铁心模型的局部损耗进行实验测试,验证了改进模型的有效性。

Abstract:There is plenty of elliptical magnetic flux density (B) in the yoke and tooth roots of the induction motor stator, the rotational losses are greater than alternating ones, and therefore, the accurate calculation of rotation loss is the premise and foundation of the optimum design of the motor. Based on the 2D rotational magnetic properties measurement system, RPT, Brockhaus in Germany, the rotational loss in the non-oriented electrical steel sheet was measured and analyzed in this paper. By studying the traditional Bertotti’s model and Steinmetz equation, this paper put forward the improved models of core loss estimation for elliptic B locus. In order to verify the validity of the proposed model, a B-H vector sensor was set up to test the local losses in an induction motor stator core.
