The permanent magnet motor has the advantages of high power density, safe operation and simple maintenance, and so on. Based on the analysis of the three-dimensional magnetic field distribution characteristics of permanent magnet synchronous motor (PMSM), permanent magnet DC motor is used as an example, The dynamic finite element analysis model of permanent magnet DC motor is characterized by the new interpolation motion boundary method to solve the rotor motion. The commutation law of the winding is calculated according to the actual brush width and winding distribution. Through the finite element analysis model, the current-torque characteristics, taking into account the cogging effect and commutation caused by the torque ripple, in-depth study of permanent magnet DC motor performance is important. The analysis method used in this work can be used to analyze the whole winding permanent magnet motor, can also analyze the ordinary DC motor, the simulation results prove the accuracy of the algorithm, the electromagnetic field numerical calculation method for permanent magnet motor design and performance analysis is important Guiding significance.
