A Gramme machine, Gramme ring, Gramme magneto, or Gramme dynamo is an electrical generator that produces direct current, named for its Belgian inventor, Zénobe Gramme, and was built as either a dynamo or a magneto. [1] It was the first generator to produce power on a commercial scale for industry.
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) 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 ...
DNADynamo is a general purpose DNA and Protein sequence analysis package that can carry out most of the functions required by a standard research molecular biology ...
The dynamo theory describes the process through which a rotating, convecting, and electrically conducting fluid can maintain a magnetic field over astronomical time scales. A dynamo is thought to be the source of the Earth's magnetic field and the magnetic fields of Mercury and the Jovian planets.
Similar to other road-going traction engines, showman's engines were normally distinguished by the addition of a full-length canopy, a dynamo mounted in front of the chimney, and brightly coloured paintwork with ornate decorations. The dynamo was used to generate electricity to illuminate and power various fairground rides.
In physics and in particular in the theory of magnetism, an antidynamo theorem is one of several results that restrict the type of magnetic fields that may be produced by dynamo action. One notable example is Thomas Cowling 's antidynamo theorem which states that no axisymmetric magnetic field can be maintained through a self-sustaining dynamo ...

DYNAMO (DYNAmic MOdels) is a simulation language and accompanying graphical notation developed within the system dynamics analytical framework. It was originally for industrial dynamics but was soon extended to other applications, including population and resource studies [ 1 ] [ 2 ] and urban planning.
