The finite element analysis of the electromagnetic fields of permanent magnet linear synchronous motor

The permanent magnet linear synchronous motor is different from the traditional rotating motor. This essay introduces its structure and the finite element analysis,uses ANSYS to establish the finite element model of the motor,calculates the electromagnetic fields in the motor,obtains the magnetic flux distribution,the magnetic flux density and the magnetic field strength through post- treatment,obtains the characteristics and rules of the magnetic fields' distribution and provides the basis for the motor's subsequent optimization of the design and improvement of the performance.
