摘要：

This paper investigates that effect of neutral voltage on shaft voltages. The shaft voltages are expected to provide cause of bearing currents. The bearing currents damage bearing in motor. We expect neutral voltages to cause shaft voltages. Thus, we construct circuit of interior motor. And we predict generation of shaft voltages by simulation using the circuit. Then we measure the neutral voltage and draw a comparison between predictive value and measured value. As a result, we can confirm connections between shaft voltages and neutral voltages.
