Abstract (en)
[origin: DE19726387C1] The motor has a collector and a shaft (9) supporting the armature and the collector, supported in a bearing (10) with a sintered bearing sleeve (12) impregnated with a lubrication medium. A rotary component (25), e.g. a ring disc, between the bearing sleeve and the collector is provided with a surface coating (26) of a material with a surface tension which is less than that of the lubrication medium.
