電動モータ用のための整流子
Document Type and Number:
Japanese Patent JP2005528072
Kind Code:
A
Abstract:
The commutator has a cylindrical collector ( 1 ), disposed on a motor armature shaft, and electrical-contact means ( 4, 5 ), which during one rotation of the collector ( 1 ) touch at least two each of a plurality of commutator laminations ( 3 ) that are present on the collector ( 1 ) and thereby establish an electrical connection between the applicable commutator laminations and external current connections ( 21, 22 ). The electrical-contact means becomes especially low-wearing because the electrical-contact means comprise at least two electrically conductive cylinders ( 4, 5 ) disposed in line with one another in the axial direction of the collector ( 1 ), the longitudinal axes ( 6, 7 ) are parallel to the longitudinal axis ( 2 ) of the collector ( 1 ); and that the at least two cylinders ( 4, 5 ) are placed relative to the collector ( 1 ) in such a manner and have a diameter such that the collector ( 1 ), in its rotation, rolls over the inside faces ( 8 ) or the outside faces of the at least two cylinders ( 4, 5 ), and in the process each of the cylinders ( 4, 5 ) is touched always by only one lamination ( 3 ) of the collector ( 3 ).
