Title  Surface mounted PMSM base on characteristics of finite element analysis method
Abstract In this paper, the principles and design surface mounted permanent magnet motor is analyzed and studied. And the finite element model based on magnet motor is founded. Finite element analysis method is a recognized high precision and strong function, the calculation of tools, has strong applicability and wide generality, application scope is very broad. It can consider the magnetic field of permanent magnet motor armature reaction of various factors. Additionally, this dessertation describes the use of research software features, functions and usage ANSOFT describes in detail the use of software processes and operation of the interface. Through the ANSOFT ,model could be set up, after that we can operate the definition of material properties and model attributes. By splitting zoned network and loading boundary conditions, partial differential equations is founded. With further handling,we can obtain a permanent magnet synchronous motor gap in the distribution of the magnetic field lines and magnetic flux density distribution and motor torque , EMF, graphs winding flux. For further analysis surface mounted PMSM provides a theoretical basis.
