Abstract :
In this paper a torque analysis of an axial field PM synchronous motor based on finite element method (FEM) is presented. The subject of study is an attractive, special type of motor, assigned to EV drives. The quasi-3D method which is adopted for this analysis is consisted of a series of 2D FEM calculations of the magnetic field in the whole three dimensional radial domain of the axial field PM motor. The magnetic field distribution is calculated at different armature currents and different rotor displacements for all five segments of the motor. Using the results from the finite element analysis (FEA) the electromechanical characteristics of the motor are going to be presented and a performance evaluation of the motor is carried out
