Most of appliance in industries and home have used single phase induction motor. Especially home appliance like compressor or pump in air conditioner has single inducion motor. Although this motor is used many fields, Not many researches try to study this machine. This paper compares the characteristic of motor according to the number of slots. And then find the most suitable the number of slots. When the number of slots is changed, not only torque but traits of noise and vibration also would be changed. This changes can be detected by studying about torque ripple and harmonics. In the result, This paper analysis a specific frequency avoidance of single phase induction motor by the FFT analysis with B radial component at air gap. and this paper finds the number of slot which can use in specific motor more efficiency with low noise and vibration characteristic.
