A dynamo is a device that converts mechanical energy into electricity, and was the first electrical generator used to power industry:
-
-
FunctionA dynamo uses a commutator to generate direct current (DC) from the rotation of a coil.
-
HistoryDynamos were introduced in 1867 and were the foundation for many other electric-power conversion devices, including the electric motor and the alternating-current (AC) alternator.
-
-
UsageThe word “dynamo” is less commonly used today, as alternators are now the standard for large-scale power generation due to their efficiency, reliability, and cost.
-
ControlA dynamo’s control gear regulates the current output based on the state of the battery and the demands of the electric system.
