What is Acoustic Measurement of Electric Motors about?

This document discusses measurement techniques for vibrations, acoustic noise, and resonant frequencies of electrical machines like induction motors. It presents a laboratory setup using digital signal processing to efficiently measure vibration and noise signals from multiple sensors simultaneously. Experimental results are shown for a 10hp squirrel cage induction motor to analyze the effects of voltage, load, and sound fields on vibration levels and noise radiation patterns. The goals are to better unders
