Abstract :
The paper proposes a method for modeling electromagnetic forces and analyzing the vibrations in synchronous motors with permanent magnets. A theoretical numerical model (based on finite element analysis of magnetic field and MATLAB/SIMULINK uses) was developed permitting study of the rotor´s vibration and the effects of the motor feed on it. We propose the realization of an algorithm that allows the calculation of the current to obtain a better behavior of the motor. It is considered that the radial forces give the vibratory behavior and the ripples of the tangential force produce ripples of the torque.
