Abstract :
This paper describes the reduction of noise in a linear induction motor (LIM) used in a linear motor car. The relationship between the core material of a LIM and the noise was examined. The frequency of both the noise and the electromagnetic vibration were analysed. It was established that the noise in the LIM was generated by the electromagnetic force rather than by the magnetostriction
