Differences Between Alternator and Generator
Alternator and Generator both are electro-mechanical machines which converts mechanical input to electrical output i.e., electrical energy.Though output of the both machines electrical power, there are some key
differences between alternator and generator are there in terms of design type of power etc.
What is the difference between an alternator and a generator?
Alternator vs Generator
| Alternator |
Generator |
| Alternator generates only AC power in every condition. |
Generator can generates both AC power or DC power
But using commutator we convert to DC power.
(Can say mostly used for DC power generation.) |
| Alternator generates higher output than Generator. |
Generator generates lower output than Alternator. |
| Alternator generates alternating EMF at its output terminal. |
Generator generates constant EMF at its output terminal.
But internally it is alternating in nature. |
| Alternator has stationary Armature and rotating magnetic field. |
Generator has stationary magnetic field and rotating
Armature for high voltage output but in case of low voltage
output rotating armature and rotating magnetic field are used. |
| It works on faraday law of electromagnetic induction. |
It also works on faraday law of electromagnetic induction. |
Alternator has DC field which generates constant magnetic
field in Armature. |
Generator has permanent magnet which generates constant
magnetic field in stator. |
| In alternator we take supply from its stator. |
In generator we take supply from rotor.
It is a major difference between alternator and generator. |
