<p>An improvement in dynamoelectric machines is disclosed in which the brush pigtail terminal junction is electrically isolated from the brush holder and other conductive parts of the machine. The member which supports the junction connecting the brush pigtail and the lead from the stator includes an insulator which electrically isolates the junction. The insulator eliminates the relatively low impedance electrical path between the brush terminal and the commutator through the brush holder, preventing damaging arcing between the commutator and the brush holders.</p> |
