Abstract
The permanent magnet linear motor is a kind of new electrical engineering that has the very high fixed position accuracy.The differents between the permanent linear motor and the type of non-permanent is that it adopts thepermanent be the source of dlux Opposite in traditional resolution method,Finite element analysis can shorten the design period of the electrical engineering and reduce to the design cost,it also can get the analysis of a precision tu the magnetic field and fotce of the linear motor the ansys8.0 is a finitr element analvtical software.
Throught the method of the Finite element for the electromagnetic analysis,we use ANSYS8.0 creat a model for the Permanent magnet lineat motor with finite element method.We analysis its 2-D setaic magnetic and get the first result. Then we analysis the force field by finish the analysis of its magetic field We calaulate the thrust and normal force combining the analysis of the permanent magnet linear motor,study the relationship between thecurrent and thrust,normal force.The work for this paper can give some help and advice to the study and design of the permanent linear motor
