摘　　要：如何考虑磁场饱和的影响是当前电机设计中一个亟待解决的重要问题。近年来提出的冻结磁导率技术越来越多地被应用到电机负载电磁性能和参数计算中。本文详细阐述了冻结磁导率的原理及其在各种电机中的应用现状。研究表明,冻结磁导率技术可以用来精确分离各种电机负载状态下的电磁分量,如磁场、磁链、电感、转矩、转矩波动、反电势和端电压、弱磁性能以及径向力等均可以用冻结磁导率技术预测,并用来辅助电机及其驱动控制系统的设计。因此,冻结磁导率技术为高性能电机的研发提供了一个全新的方法。Magnetic saturation is one of the major challenges for all electrical machines and makes it much more difficult to design high performance electrical machines. Frozen permeability （FP） technique has recently been developed to predict the on-load components of electromagnetic qualities while considering the influence of magnetic saturation. In this paper, the FP technique and its applications in various electrical machines are comprehensively reviewed. It shows that the FP technique is able to accurately separate on-load magnetic field, flux linkage, and inductance components in all types of electrical machines. These on-load field components and parameters can be further utilized to investigate various on-load performance, such as on-load torque and torque ripple components, on-load back EMFs and voltages, flux weakening performance, radial force distribution, et al. The accurate on-load parameters can also be used to improve the machine models and controls. Hence, FP technique provides a holistic approach to the development of high performance electrical machines.
