ABSTRACT
According to Mr Ströberg, the Managing Director of Carbex, the company was founded in 1887 and has always been in the business of making carbon brushes. Carbon brushes constitute an essential part of electric motors and generators and are also used for the transmission of electric signals. Carbon brushes are made in all sizes, from those needed by very small motors to the biggest ones in power plants. A patent for the first self-adjusting carbon brush was granted to the founder of Carbex, Mr Loewendahl, in 1909. The patent has since then been under constant improvement. Carbex’s other main product is slide rings, a device making it possible to lead electricity and electronic signals through rotating equipment, such as power turbines, car steering wheels and radar to mention a few applications. Both these products are made for new machines as well as replacements for old ones. Carbex is also a wholesale supplier of all kinds of parts for electrical motors and engines. The wholesale business is some ten years old, and is a response to the demand for replacing not only the carbon brushes in a broken machine, but also other parts broken at the same time. Carbex makes the carbon brushes from a sintered mix of carbon and copper and silver respectively. The production is mechanized and automated as well as manual. Much of the machinery for production is made in-house.
