SMALL-SIZED MOTOR |
摘要 |
<p>The present invention provides for its object a compact electric motor effective to provide a high reliability against the leakage of grease from a bearing on one side adjacent the output shaft or the ingress of oil from a counterpart machine. The compact electric motor 1 has a wall 14 having a predetermined gap around an output shaft 3 between a commutator 7 and a bearing 6, wherefore in the event of leakage of grease from the bearing 6 on an output side or ingress of oil from the counterpart machine, it is possible to prevent deposition on the commutator 3 and the brush 5 and, hence, to avoid an abnormal wear of the brush 5 and reduction in performance of the compact electric motor 1. <IMAGE></p> |
