Abstract

The paper presents the methodology for obtaining the level of noise in three-phase induction motors with squirrel cage rotors. Investigations include a single-speed motor with 3000 r/min and a two-speed motor with 750 and 1500 r/min. The investigated motors (manufactured by a Romanian company) were placed in a semi-anechoic chamber to determine the noise-to-frequency characteristics (spectrograms). The spectrograms were analyzed and the results and conclusions are presented in this paper.
