Unformatted text preview: Alternators An alternator/generator An alternator is a device that is used to charge the battery in our automobiles. An alternator is comprised of the following parts: The Rotor- shown below, is a belt-driven computer controlled electromagnet. It has a large coil of wire, shown with red wiring, connected to the two brass slip rings shown on the left of the photograph. The coil of wire in enclosed inside of an iron frame with twelve pole pieces (the pointed shaped pieces in the photograph). The iron frame strengthens the magnetic field, and when the coil is energized with power and ground, it produces twelve very strong magnetic fields at 30 degree intervals. The rotor also has at least one cooling fan attached to it. The fan directs air across the rectifier bridge to cool it. The Stator- The stator is comprised of three evenly-spaced large coils of wire positioned inside a laminated iron frame. The iron frame helps strengthen the rotor's electromagnetic field. As the rotor is spun inside the stator, AC current is induced into the three stator windings by the rotor's...
