A dynamo is an electrical generator that creates direct current using a commutator. Dynamos were the first electrical … See more

The operating principle of electromagnetic generators was discovered in the years 1831–1832 by Michael Faraday. The principle, later called Faraday's law, is that an electromotive force is generated in an electrical c… See more

The word 'dynamo' (from the Greek word dynamis (δύναμις), meaning force or power) was originally another name for an electrical generator, and still has some regional usage as a replacement for the word gener… See more

The electric dynamo uses rotating coils of wire and magnetic fields to convert mechanical rotation into a pulsing direct electric current through Faraday's law of induction. A dynamo machine consists of a stationary s… See more

Dynamos, usually driven by steam engines, were widely used in power stations to generate electricity for industrial and domestic purposes. They have since been replaced by alternators.
