A dynamo, a type of electrical generator, is used in many ways, including:
-
Early power generationDynamos were the first electrical generators used to power industry and machinery.
-
Electric vehiclesDC dynamos convert the mechanical energy of a vehicle’s motion into electrical energy that can power the vehicle or be stored in batteries.
-
Portable powerDynamos can be used as portable power sources for camping, construction sites, and emergency backup power.
-
Foundation for other electric-power conversion devicesDynamos were the basis for the development of other electric-power conversion devices, such as the electric motor, the alternating-current alternator, and the rotary converter.
A dynamo works by using a commutator to convert mechanical energy into direct current. It uses rotating coils of wire and magnetic fields to create a pulsing direct electric current.
