Abstract :
In this work we present the study and identification of the frequencies of the signals implied in a sine PWM control based on DSP of electrical machines, especially in a three-phase motor of induction. We will also try this identification will be used as a basic for a later analysis of the influences they will originate in the acoustic noise level emitted by the machine.
