These days, a quiet induction motor is in great demands. In low speed motor with 4 poles and 6 poles, electromagnetic noise is predominant in acoustic noise. Most electromagnetic vibration and noise is originated from combination of harmonic fluxes in the air gap. Space distribution of fundamental and harmonic fluxes was studied using search coil, FEM analysis and equations. Harmonic fluxes including fundamental one were measured with 36 search coils on inner surface of the stator teeth. From this experiment, flux space distribution in each flux frequencies was obtained. Flux space distribution was also analyzed by FEM. These results were analytically checked by mathematical equation. From these stuff, space flux distribution mode, for various harmonics was confirmed. This result will be useful for quiet motor design.
