Concept of AC Generators

When shopping for Power Generators (AC generators) you may want to know how the Electricity Generators categorized and even get some deep look inside AC generators to know why we need to seek certain brands with certain qualities and set an investment point to avoid over investing. Also, it can help when you want to do maintenance to AC generators .

Two main categories we have from the generated electricity prospective: AC and DC.

AC generators or Alternative Current Generators, also know as alternators are what you usually need to power your home, camp or jobsite, which operate on the same fundamental principles of Electricity Generation using electromagnetic induction.

AC generators can generate electricity by rotating a coil in the magnetic field or by rotating a magnetic field within a stationary coil. The value of voltage generated by AC generators depends on the number of turns in the coil, strength of magnetic field and speed at which the coil or magnetic field rotates. Simply, the quality of the AC generators are managing by maintaining the quality of material of core coil, magnetic components and the prime mover (Motor) to ensure the production of high quality long lasting AC generators .

portablegeneratorinfo.com gives a deeper look into commercial AC generators. Any of the commercial AC generators consist of a stationary stator and a rotor mounted within the stator. The stator contains a specific number of coils, with a specific number of windings. Similarly, the rotor is consisted of specific number of field poles, each with specific number of windings. To start power generation AC Generators need to provide rotation to the rotor.

Rotor - The rotor is the source of the magnetic fields. When the rotor is rotated (by AC generators built in motor), AC is induced in the stator.

Stator - The frame assembly is the main component of the stator. Insulated windings (or coils) are placed in slots near an air gap in the stator core (this is core body of  AC generators ).  One end of each coil is connected to a common neutral terminal. The other end of each coil is connected to separate terminals. Conductors are attached to the four terminals carry the current to the AC generators switchgear the to the output or the load.
