The torque capability of traditional Permanent Magnet (PM) machine is independent of pole number. Limited by torque produce principle, it is very difficult for traditional permanent magnet machines to substantially improve its torque density. Magnetic field Modulation Permanent Magnet (MMPM) machine’s torque principle is totally different from that of traditional PM machines, and the torque density of magnetic field modulation machines is much higher than that of traditional PM machines benefited from its special operation principle. MMPM machines can meet the demand for high-grade, precision and advanced applications, as well as for regular industrial applications. If the MMPM machine can be widely used in mass production and in many applications, huge amount of weight and cost reduction will be realized. The MMPM machine is getting more popular in recent years, but research level is in the initial stage. This project focuses on fundamental principle and application technology of the MMPM machines. Analyses of the principle and output characteristics of the MMPM machines will be done in this project, then the theory system of the MMPM machine will be explored; The design and optimization method will be analyzed, and then propose the general design criterion for the MMPM machines. A novel MMPM topology will be presented in this project, and a special attention will be made for power factor improvement of the MMPM machine. A novel MMPM topology will be proposed, and the research on its theory and design method will be conducted. The control technology of the MMPM machines will be done as well. Finally , the theory system and design criterion of the MMPM machine will be built in the project, systematic analysis methods and key application technologies for the MMPM machines will be performed as well.
