Whats the Difference Between Generator and Alternator?
Generator is a generic class of devices, while the alternator is a type of generator producing AC current.
• Alternators use voltage regulators and rectifiers to create a DC output, while in other generators DC current is obtained by adding a commutator or AC current is produced.
• Alternator output can have varying frequencies due to changes in the rotor frequency (but it has no effect because the current is rectified to DC), while the other generators are operated to a constant frequency of the rotor shaft.
• Alternators are used in automobiles, to generate electrical power.
Generator vs Alternator
Broadly defining, a generator is a generic term for a device that converts mechanical energy to electrical energy, and an alternator is a type of generator that generates an alternating current.
