Electric Generator
Since the first motor vehicles to approximately the 60's tended to use dc electric generators with electromechanical regulators. These have been replaced by the alternators with built-in rectifier circuits, which are less expensive and lighter and final production is equivalent.
Automotive alternators provide power to the vehicle's electrical system and recharge the battery after starting.
The rated output is normally in the range of 50-100 A at 12 V, depending on the designed electrical load for the vehicle. Some vehicles now have many household appliances and air conditioning, which is a high load on the electric system. Large commercial vehicles are more likely to use 24 V electricity generators to provide enough energy in the starter motor to maintain a large diesel engine.
Vehicle alternators do not use permanent magnets and usually only use 50-60% efficiency over a wide speed range. Motorcycle alternators often use permanent magnet stators made with earth magnets because they can be smaller and lighter than other types.
Some of the smaller electrical generators are commonly found in the lights of the bike. These tend to be 0.5 ampere, permanent magnet alternators. Providing 3.6 W to 6 V or 12 V.
When activated by the pilot, the efficiency is rather low, so these can be incorporated earth magnets and are designed and manufactured with great precision. However, maximum efficiency is only about 80% in the best cases - 60% is more typical - in part due to tire rolling friction at the interface of the generator set of a bad alignment, the small size of the generator, taking losses and cheap design.
Sailing yachts may use water or wind electric generator to use them to charge the batteries. A small propeller, wind turbine, is connected to a low-power alternator and rectifier to supply currents up to 12 A, how typical cruising speeds.
A generator is any device capable of maintaining an electrical potential difference between two points, called centers, terminal or terminals. Electric generators are machines designed to transform mechanical energy into electricity. This transformation is accomplished by the action of a magnetic field on electrical conductors arranged on a plate (also called a stator). If mechanically relative movement between the conductors and the field, generate an electromotive force (EMF).
They are classified into two types: primary and secondary. They are the primary generators that convert energy into electrical energy of any other nature or which are available initially, while the side give a portion of the electricity that have previously received. The specific devices will be grouped according to physical processes that they are based.
