Abstract

In suspended permanent magnet maglev trains, the magnetic field generated by hollow-type permanent magnet synchronous linear motors is one of the main sources of low-frequency electromagnetic fields. To investigate the magnetic field generated by the linear motor in the train, this paper first establishes the 2D and 3D models of the linear motor using ANSYS EM software. Then, the electromagnetic simulation of the magnetic field of the linear motor is performed under conditions of no load and full load. Next, the magnetic field of the motor is measured using a six-channel high-precision magnetic field test system, and the simulation and measurement results are compared. The result analysis indicates that the energy distribution of the electromagnetic field generated by the linear motor is uniform and that the magnetic induction intensity falls within the range of 0 to 1.1 T. Meanwhile, the linear motor can form a closed loop with a small electromagnetic field energy leakage. Combined with its installation structure, the radiation to the surrounding environment is weak, and the interference with the normal operation of the train control communication equipment is minimal. This study lays a foundation for analyzing electromagnetic distribution on the surface of the suspended permanent magnet maglev train. It also provides a basis for formulating various electromagnetic radiation protection measures and provides theoretical support for developing suspended permanent magnet maglev trains.
