Siemens' Self Exciting Dynamo,1873

An early type of Siemens' Self Exciting dynamo (1873) with drum-wound armature and bar commutator. A dynamo is an electrical generator that creates direct current using a commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current alternator, and the rotary converter. Charles William Siemens (April 4, 1823 - November 19, 1883) was a German-born engineer who for most of his life worked in Britain and later became a British subject. The regenerative furnace is his greatest single invention using the Siemens-Martin process. The electric pyrometer, which is perhaps the most elegant and original of all his inventions, is also the link which connects his electrical with his metallurgical researches. Siemens pursued two major themes in his inventive efforts, one based upon the science of heat, the other based upon the science of electricity; and the electric thermometer was, as it were, a delicate cross-coupling which connected both. He died in 1883 at the age of 60. No artist credited, 1873.
