DC generator
1. AC Dynamo has full rings whereas DC Dynamo has split rings. 2. AC Dynamo produces alternating current whereas DC Dynamo produces direct current. 3. IN AC DYNAMO, CURRENT KEEPS CHANGING EVERY HALF OF A CYCLE WHEREAS IN DC DYNAMO, CURRENT FLOWS IN SAME DIRECTION.
There are two types of electrical generator. One is a dynamo, which produces d.c. The other is an alternator, which produces a.c.
A dynamo is an electrical generator.
The picture above is a dynamo- a large electrical generator.
Weak machines fear it because it measures horsepower and torque.
It makes AC ( alternating current ) . That's why it's called an alternator. A DC generator would usually be called a dynamo.
dynamo
As long as the direction in which the dynamo is turned remains the same then yes, it is essentially the same as a D/C generator, albeit a small, weak one. If the rotational direction of the dynamo keeps changing it becomes an A/C generator (the current flows one way, then the other). This would require some form of charging capacity such as a battery or capacator in order to have any usefull purpose. Generally speaking, A/C generators & inverters either 1)are powered by fuel engines, or 2)require much more input than a dynamo could feasibly provide in order to carry out their particular function. A typical example of an A/C generator is a Welding machine. (You could not run a welder off a dynamo!)

The generator
Generator or dynamo
The first dynamo or electric generator was invented by Michael Faraday in 1831. Although it functioned as one, it was not a pure dynamo because it lacked a commutator.
