An electrical generator is an alternator that converts the energy of mechanical to electrical energy in the form of alternating current. An alternator which is linear or rotating in the armature with a stationary field of magnet is used in many fields. In principle any electrical AC generator can be called an alternator. But usually the term basically refers to small machines which are rotating and are driven by automotive and other internal engines combustion.
Generator and Alternator Difference
An alternator that uses a magnet which is permanent for its field is called a magneto. Alternators in power stations generally are driven by steam turbines known as turbo-alternators. A very Large 50 or 60 Hz alternator of three-phase that is in power plants generates most of the world's electric power. The power which is generated is distributed by electric grid power.
A conductor moving relative to a magnetic field develops an electromotive force, EMF in its law of Faraday's. This reserved EMF and its polarity moves under poles of magnetic polarity. We can that typically a rotating magnet is known as the rotor turns which is within a set of stationary of conductors wound in coils on a core of iron is known as the stator. The cuts of the field which is across the conductors generate an induced EMF that is electromotive force as the input of mechanical forces causes the rotor to turn.
The magnetic fields induce an voltage of AC in the stator windings since the currents which are present in the stator windings, vary in step with the rotor position because an alternator is a generator synchronous.
Difference Between DC Generator and Alternator
The generator is a device that converts power that is mechanical energy into power electrical for use in an external circuit. The electromagnetic generator was the first Faraday disk and it was invented in British by scientist Michael Faraday in 1831. The Generators which provide nearly all of the electrical power for grids.
The conversation reverse of energy which is electrical and is into energy which is mechanical is done by an motor which is an electric motor and at times we can say the generator and motors have many similarities. Many of the motors can be mechanically driven to generate electricity frequently that is they make manual acceptable generators.
Generator Alternator Difference
One of the major differences which is between the generator and alternator is that in alternator the armature which is stationary and the system of field rotates whereas in the generator armature rotates and the field is very stationary. The armature which we have discussed is the alternator which is mounted on the element which is a stationary element known as the field and stator winding which is on a rotating element. While if we notice then the connection of a generator is just the reverse of it. The other differences which are between them are shown below in the comparison chart mentioned in the article's end.
The generator and the alternator both work on the principle of law of Faraday which is of electromagnetic induction. The induced generator which has both the direct and alternating current and the alternator produces only current which is alternating. The generator's rotor is placed inside the magnetic field which is stationary.
The magnetic field which is stationary is produced by the poles of the magnet. The rotor generally moves inside the field of magnet which later intersects the line of magnet of force which induces the wire current.
Every rotation which is half of the rotor changes the direction of the current which later causes the current which is alternating. For getting the current which is alternating in nature the ends of the circuit is directly connected to the load. But for producing the current which is direct the ends of the wire are also connected to the commutator. The commutator converts the current which is alternating into direct current.
State the Difference Between Generator and Alternator
The generator which is synchronous or we can say Alternator is a machine for converting the power which is mechanical from a prime mover to an AC power of electrical at a specific frequency and voltage. The alternator which is Three-phase is used because it has many advantages of distribution. That can be said as the generation and transmission. For the power which is in bulk generation a large alternator is used in the hydro, thermal and nuclear power station.

The generator generally converts the energy which is mechanical into energy which is electrical or power. The generators working is based on the principle of law of Faraday of electromagnetic induction that is whenever the conductors cut the magnetic flux which is EMF induces. This EMF causes the flow of current if the conductor is closed. The field which is a magnetic field and conductors are the two essential parts of generators.

An mechanics of alternator which converts the energy which is mechanical from a prime mover into the AC on the other hand the generator converts the energy which is mechanical from the prime mover into an DC or AC.
The induced alternator AC whereas the generator which causes both the AC and DC power. The generator which produces the current which is alternating which is converted into DC by the help of the commutator.
The alternator that has a magnetic field with rotating field on the other hand the generator has a magnetic field which is a rotating field for the high voltage generation and the voltage which is low and stationary magnetic field is used.
The alternator usually takes supply input from the stator whereas the generator takes input supply from the rotor.
