Abstract
ABSTRACT Existing theory for the analysis of the acoustic noise and vibration produced by single-phase induction motors is restricted to 2-pole machines (Yang, 1975). In this paper it is extended to cater for motors having any number of poles, and is then used to analyse the noise and vibration spectra of a typical 4-pole PSC motor and fan assembly. Both electromagnetically and aerodynamically generated noise and vibration are studied, with particular emphasis on the effects of rotor eccentricity, magnetic circuit saturation, and stator and rotor resonances.
