Utility and Application of a Versatile Analytical Method for MMF Calculation in AC Machines

引用

CES Transactions on Electrical Machines and Systems 2024年第1期8卷 22-31页

作者： Ze-zheng Wu Robert Nilssen Jian-Xin Shen IEEE the College of Electrical Engineering Zhejiang UniversityHangzhou 310027China the department of Electric Energy Norwegian University of Science and TechnologyTrondheimNorwayand also affiliated with the College of Electrical EngineeringZhejiang UniversityHangzhou 310027China

A versatile analytical method(VAM) for calculating the harmonic components of the magnetomotive force(MMF) generated by diverse armature windings in AC machines has been proposed, and the versatility of this method has been established in early literature. However, its practical applications and significance in advancing the analysis of AC machines need further elaboration. This paper aims to complement VAM by augmenting its theory, offering additional insights into its conclusions, as well as demonstrating its utility in assessing armature windings and its application of calculating torque for permanent magnet synchronous machines(PMSM). This work contributes to advancing the analysis of AC machines and underscores the potential for improved design and performance optimization.
