6.ELECTROMAGNETIC MECHANISM

6.1 Electromagnetic Generators

Transform mechanical energy into electricity. There are two types of generators, depending on the type of current that is produce. Direct current called dynamos, and produce alternating current are called alternators.

Dynamos:

Consists of a magnet and rotary coil. the coil is located between the two poles of the magnet.
The ends of the coil have two semi.circular conductor, wich form communator.

Alternators:

Is almost identical to a dynamo, exept for the commutator, which consists of two metallic rings connected to carbon brushes. Produce alternating current.
