Abstract :
This paper employs analysis of electromagnetic force harmonics to determine a stator/rotor slot combination for a reduction of electromagnetic noise in induction motors. Three kinds of slot combinations are investigated to improve existing designs of induction motors. The effect of the proposed slot combination technique used for redesigning motors is verified by evaluating the calculated electromagnetic noise and comparing with the measured overall acoustic noise of the motors. The measured acoustic noise is also compared with that of the original designs.
