Abstract
This Paper presents the effects of the Parasitic Torques in a single phase induction motor, on the Vibration and Noise that’s generated from choosing unsuitable value of running capacitor. In this research a computer program has been developed of the motor Sound. The sound signal is measured by using a sound level meter and then it is transmitted to the computer through a data acquisition card and then the signal has been analyzed. In addition to that the Vibration signal has been analyzed. Experimental results has been obtained in the Anechoic Chamber Laboratory, It has been found that the optimum value of the running capacitor for this induction motor was 23μf .This gives minimum Parasitic Torques whose frequency is twice the input source frequency, and therefore minimum noise and vibration caused by this Parasitic Torque has been obtained.
Key words: "Parasitic Toque for single phase induction motor"
