Why you need Alternator & what are the uses
An alternating current generator is an energy converter that generates alternating current by converting mechanical energy into electrical energy. In cars, an alternator is used to charge the battery and power the electrical system while the engine is running. In our landfill we transport used alternators for many types of vehicles. You can pull out your own used alternator, or we can pull it out for you.
The alternator consists of a stator, which is a fixed set of wire windings in which the rotor rotates, which is an electromagnet powered by a small amount of electricity through carbon or copper-carbon brushes (contacts) in contact with two rotating metal contact rings on its shaft. The rotation of the electromagnet inside the stator coils generates much more electricity inside these coils. Electricity is an alternating current, and the direction of its flow changes back and forth every time the rotor rotates. It must be rectified (direct current). A dynamo generates direct current, but it is less efficient, especially at low engine speeds, and weighs more than an alternator. The indicator light on the dashboard lights up when the battery is not charging enough. There may also be an ammeter that shows how much electricity is being generated, or a battery status indicator is also used to display the state of charge of the battery.
However, typical alternators for passenger cars and light trucks use a Lundell or “claw-pole” design. Modern vehicles now use a compact alternator layout, while larger vehicles may have generators with protruding poles similar to larger machines.
