“…For the Type 1 rotor, the flux linkage produced by the PM is arranged against the q-axis armature flux linkage, while for the Type 2 rotor, the PM flux linkage complements the d-axis armature flux linkage. The Type 2 motor can thus be called the flux-intensifying PMa-SynRM (FI-PMa-SynRM) [26]. Assuming that the iron saturation and the cross-coupling effect are neglected, the stator dynamic voltage equations for synchronous machines in the d-q frame [27,28] can be expressed as:…”

This paper analyzes the performance of a synchronous reluctance motor (SynRM) equipped with a limited amount of a permanent magnet (PM). This is conventionally implemented by inserting PMs in rotor flux barriers, and this is often called the PM-assisted SynRM (PMa-SynRM). However, common PMa-SynRMs could be vulnerable to irreversible demagnetization. Therefore, motor performance and PM demagnetization should be simultaneously considered, and this would require the PM to be properly arranged. In this paper, various rotor configurations are carefully studied and compared in order to maximize the motor performance, avoid irreversible demagnetization and achieve higher PM utilization. Moreover, the field weakening capability is investigated and improved by regulating armature excitation. A particular rotor type with flux intensification was found to possess higher PM utilization, lower demagnetization possibility with fairly high performance. Thus, suitable rotor configurations are recommended for certain applications.

Summary Flux intensifying interior permanent magnet synchronous machine (FI‐IPMSM) was designed to improve the characteristic of conventional permanent magnet machine, especially, in field weakening region. Increasing a saliency ratio is the main method to achieve this target which leads to increasing reluctance torque than magnetic torque and so improving the machine performance. In this paper, the characteristics of FI‐IPMSM are investigated. The effect of PM material, PM width, PM thickness, flux barriers width, and iron bridge thickness on the machine parameters is studied. Machine inductances, no‐load and full‐load characteristics are analyzed. A comparison is carried out between the FI‐IPMSM and conventional IPMSM to evaluate the improvement in machine performance. Two‐dimensional time‐steeping finite element method (FEM) is employed in analysis of the FI‐IPMSM and conventional IPMSM.
