Abstract Considering the influence of the permanent magnet motor on the environmental magnetic field, theoretical modeling of the static two-pole parallel magnetized permanent magnet motor was proposed, and the magnetic field theoretical model of the internal and external motor domains (rotation shaft, permanent magnet, air gap, stator, environment) was proposed. Meanwhile, the magnetic field distribution was also analyzed, and the finite element method and experiment were used to verify the correctness of the model in this paper. It provides a reference for the analysis of the environmental magnetic field of the motor, the magnetic field compensation of the geomagnetic equipment, and the optimization of the external magnetic flux leakage.

Key words： Permanent magnet motor finite element method Laplace's equation external magnetic flux leakage
