This paper reports the three-dimensional magnetic field analysis using the magnetic network method for evaluation of parameters and performance of a claw pole permanent magnet machine. The magnetic network model is built based on the principle of equivalent magnetic flux pipes and the network equations are derived to solve the nodal magnetic scalar potentials, which are used to calculate the magnetic flux flowing through different cross-sectional areas. The results are validated by 3D finite element method. The magnetic network technique has the advantage of combining the speed of the conventional magnetic circuit method and the computational accuracy of finite element analysis.
