Analysis of the Sound Field Emitted by a Doubly Salient Switched Reluctance Motor Using Acoustic Intensity Measurement

Abstract

We propose in this article to apply the technique of acoustic intensity measurement for the analysis of the sound field emitted by the doubly salient switched reluctance motor (DSSRM).The measurements got here try to make profitable the power of this technique by using a Matlab code in order to obtain a visualization of the sound images for given frequencies, of the principal sources of vibrations present in this motor. This technique allowed calculating the sound power of the acoustic noise radiated by each face of the motor, which is calculated by using the discrete points method. It can be an original and a complementary experimental method to traditional used up to now for this kind of motor
