Electric motor with commutator |
摘要 |
An electric motor comprising a commutator and lever brushes which resiliently press thereagainst and are pivotable about a pivot axis, a connection line which extends in a direction perpendicular to the pivot axis between the center point of a brush contacting surface and the pivot axis being tangential to the outer surface of the commutator. Such a brush assembly is to be made smaller in size. Each lever brush comprises a bearing bush rotatably arranged to be coaxial to the pivot axis, as well as a shaped body which is made from a conductive material and is firmly connected to the bearing bush. The shaped body forms the brush contacting surface and has a connection point which is in direct electrical contact with the brush contacting surface for electrically connecting the lever brush. The bearing bush is made from a material which is more stable than the shaped body.
