| 摘要 |
The present invention relates to a motor for preventing electric erosion generated between a ball and the outer and inner races of a bearing due to a current when instantaneous short is generated in a condition where a potential difference by grease in the middle of the ball and the outer and inner races of the bearing of a bearing cover combined with the upper and lower parts of a housing which is a nonconductor. The motor includes the housing, a rotor, a housing cover, bearings, and a ground member. |
