Abstract :
This paper describes a new type of noise reduction technique for induction motors. The traditional motor has the equi-slot pitched design. This paper takes an inequality slot pitched rotor, and makes energy distribution for a wide frequency range. These ideas were proved by the power spectrum and autocorrection function of information theory, and tested by real production motors
