| Abstract: | From the point of shaft current producing theory,the mechanism and harm of shaft current of variable-frequency motor is analyzed,and useful testing analysis method of shaft current is introduced. At last,the measures of restraining power supply harmonic,installing carbon brush and applying spike voltage absorber（ SVA） are proposed to prevent variable-frequency motor from harming. |
