A permanent magnet is both a magnetic source and a component of the magnetic circuit in an electric motor. The magnetic properties of permanent magnets are not only related to the manufacturing process of the production plant, but also to the shape and size of the permanent magnet, the capacity of the magnetization machine, and the magnetization method. The specific performance data is highly discrete. Moreover, the magnetic flux and electromotive force that permanent magnets can provide in the motor also vary with the material properties, size, and motor operating state of the remaining parts of the magnetic circuit. In addition, the magnetic circuit structure of permanent magnet generators is diverse, and the leakage magnetic circuit is very complex and accounts for a large proportion of leakage magnetic flux. The ferromagnetic material part is relatively easy to saturate, and the magnetic conductivity is nonlinear. These all increase the complexity of electromagnetic calculation for permanent magnet generators, making the accuracy of the calculation results lower than that of electric excitation generators. Therefore, it is necessary to establish new design concepts, reanalyze and improve the magnetic circuit structure and control system; It is necessary to apply modern design methods and research new analysis and calculation methods to improve the accuracy of design calculations; Advanced testing methods and manufacturing processes must be studied and adopted.
