Abstract :
In motor applications, noise and vibration reduction techniques should be implemented in its design stage for improved performance. Motor vibration is mainly induced from stator, especially from teeth excited by electromagnetic force. In this paper, to provide a useful noise reduction technique, electromagnetic force acting on a motor tooth is analyzed as an acoustic noise source and the result is verified by noise measurement.
