This paper presents a saturable analytical model of induction machines, with a systematic approach for segregating the electromagnetic losses. The proposed model is based on the equivalent circuit of the machine, which has been augmented to account for different loss components. The segregation of different loss components in stator and rotor have been improved by considering the loading, skin effect and field-weakening operation. The required parameters of the model are identified from a well-defined set of finite element analysis of the machine. The proposed model and the identification methodology have been tested on two different induction machines. In both cases, the finite element computations are validated with laboratory measurements, and the analytical model is validated against the finite element model. The results show that the proposed model is more accurate than the conventional ones from the literature, and thus it can be used as a component while building a digital twin of the induction machine, and inserted into a virtual simulation software for real-time thermal management for example.
