Research of Noise Spectrum Characteristics of Traction Motor System for Electric Vehicle

The characteristics of the electric vehicle traction motor system different from the traditional industrial motor system,and the noise spectrum characteristics are also differently.Researches of noise spectrum characterstics of traction motor system for electric vehicle were performed detailed.The figures of noise spectrum characteristics were received at different conditions.And the same time with the structure of the electric vehicle motor system,the noise spectrum characteristics to each of its corresponding part can receive also.
