The core loss modeling in the equivalent circuit and developing regulation methods of the core loss are among the key technologies to analyze the performance and improve the efficiency of the permanent magnet synchronous motor (PMSM). Nowadays, understanding, modeling, and regulating the core loss of the PMSM play increasing crucial roles when developing high-speed, high-efficiency, high-torque density and high-power density motors. Therefore, this thesis aims to develop generalized equivalent circuit models (ECMs) of the PMSM with predictable core loss, including per-phase ECM and d- and q-axis ECMs. Firstly, the core loss with the 3-dimensional rotating magnetic field is investigated, and the method of how to model the core loss into the ECM is developed, in which the equivalent core loss resistance is modelled as a function of the motor speed to achieve high accuracy over the entire speed operating range, and then an attempt of adopting the proposed ECM in deadbeat predictive current control to improve the dynamic response and robustness of the PMSM drive system is made. Secondly, to further increase the core loss prediction accuracy especially in load conditions, a novel generalized per-phase ECM of the PMSM with predictable core loss is proposed. Experimental tests of the PMSM prototype suggest that the prediction precision of both the core loss and the output electromagnetic characteristic is effectively enhanced over the entire speed and torque operating range. Finally, novel generalized d- and q-axis ECMs of the PMSM with predictable core loss are established to benefit motor control and enable the core loss management. Moreover, to make the most use of the stator current and decrease the electromagnetic loss of the PMSM, an improved maximum torque per ampere current control considering both the core loss and copper loss is carried out theoretically. The research results of this thesis will improve the accuracy of the ECMs and mathematical models of the PMSM, and hence provide theoretical and technical support for the improvement of the optimization methods and control strategies of the PMSM.
