Abstract
Carbon Brushes are used to supply power to rotors used in AF cameras or the heaters inside the light-sensitive drums of copying machines. Such brushes have been developed every time a new product was planned. ln the development, quality characteristics such as temperature rise, brush holder deformation, wear or sparks, etc. have been traditionally used. In this paper, the technology development of carbon brushes performed before product planning is reported using the characteristic which relates to energy transferring instead of traditionally used characteristics.
