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.
