抄録(英) | A sliding contact enables the transfer of electrical current between stationary and moving objects. In DC motors, the static part is the brush and the moving object is the commutator. DC machines are used in many fields, such as metal rolling iron processing, electric railways, and paper mails. Further, the brush-slip-ring system of a generator used in a wind power system needs a long lifespan. Thus, improved reliability and an extended lifespan are desirable qualities for sliding contact mechanisms. Recently, it became preferable to use new materials for the slip ring and brush to improve the contact reliability while increasing current capacity. This study was a laboratory-scale investigation into the effect of temperature change on a gold-coated slip ring and silver-graphite brushes, and on a silver-coated slip ring and silver graphite brushes. |
