First for the design and dimensioning of PMSM machine, we must know the distribution of the magnetic field in each part of the magnetic system and in particular at the air gap in which the energy conversion takes place. Generally, Maxwell’s partial differential equations supplemented by material’s law are used to describe the magnetic field problems. However, a numerical calculation is necessary, especially with the complex geometry of these devices. Secondly, we develop a machine Park model in relative unit to simulate a simple closed loop control imposed on the position of the PMSM rotor used in the wind energy conversion chain and this control is used to define the phase voltage have enabled to evaluate the performance of the machine. Keywords: Permanent magnet synchronous machine (PMSM), FEM analysis, Magnetic induction, Control position. 1. INTRODUCTION Currently, permanent magnet synchronous machines are increasingly used in industry because of their superior performance compared to other conventional alternate current machines like asynchronous machine. Indeed, these machine is used in trainings requiring constant rotation speed (ventilators, compressors and centrifugal pumps) and thanks to the development of power electronics, the power magnet converter machine association has found many applications in very diverse fields such as robotics, space technology and other more specific domestic applications [1]. In addition, magnet synchronous engines are used in household equipment (laundry machines), automobiles, computer and medical equipment. Finally, magnet machines are found in the production of electric energy (wind power plants) where we find that it compete with DFIG machine in this field [2]-[3], in the electric propulsion and submarine [4]-[6]. The operation of electrical machines is directly related to the distribution of magnetic field lines within their structure. Knowledge of this distribution allows to determine the dimensions necessary for their dimensioning such as flux, induction, electromagnetic torque,..etc [7]-[8]. With analytical methods, the resolution of electromagnetic systems with non-linear analytical characteristics presents calculation problems, because they do not allow taking into account the geometric specifications of the machine, as well as the nature of its materials. Nowadays, the increasing possibilities of computing and the evolution of digital methods have allowed taking account of increasingly complex phenomena and providing satisfactory solutions to a large number of problems. The finite element method (FEM) is one of the most widely used numerical methods for calculating the magnetic field in electrical machines [9]-[10]. The development of mathematical models of magnetic machines has great importance in order to analyze this type of machine and especially in the field of control. Many researchers have been interested in the modeling of magnetic machines. The most appropriate model for the study of dynamic behavior and for control is inspired by the work [11]-[12]. This paper proposes the analysis of the PMSM depending on the position of the rotor. The rotor of the PMSM uses permanent magnets mounted on the surface. Two parts are detailed. First we presented an approach adopted by FEM allows the resolution of the
