The different between of the Alternator and Generator

Difference Between Alternator And Generator

Sl. No.	Differentiating Property	Alternator	Generator
1	Definition	An alternator is a device that converts mechanical energy into AC electrical energy.	A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energy.
2	Output Current	An alternator always induces an alternating current.	A generator can generate either alternating or direct current.
3	Energy Efficiency	Alternators are very efficient.	Generators are considered less efficient.
4	Output	Alternators have a higher output than generators.	Generators have a lower output when compared with an alternator.
5	Energy Conservation	Alternators use only the required amount of energy and thus, it conserves more energy.	Generators use all the energy that is produced and so, they conserve less energy.
6	Polarization After Installation	Polarization is not required in case of alternators.	Generators need to be polarized after installation.
7	Magnetic Field	The magnetic field is rotating inside the stator of an alternator.	In case of a generator, the magnetic field is stationary or fixed where the armature winding spins.
8	Armature Movement	The armature of an alternator is stationary.	The armature of a generator is rotating.
9	Input Supply	The alternator takes input supply from the stator.	The generator takes input supply from the rotor.
10	RPM (Rotation Per Minute) Range	Alternators have a wide range of RPM.	Generators have a low range of RPM.
11	Voltage Generation	Alternators produce voltage only when needed.	Generators produce voltage at all times.
12	Size	Alternators are generally smaller in size.	Generators are larger and require more space to fit in.
13	Brush Efficiency	The brushes of alternators last longer.	The brushes of generators last lesser when compared to an alternator.
14	Charging of a Dead Battery	Alternators will never charge a dead battery	A generator can be used for charging a dead battery.
15	Uses	Alternators are mainly used in the automobile industry as a charging system for the battery.	Generators are widely used to produce large-scale electricity.

These were the main differences between alternators and generators. These alternators and generator differences are a bit in-depth to help the students get a complete idea about them. These detailed and advanced comparisons can help the students to get completely thorough with these respective topics. (Source)

• Kumparan pembangkit yang terdapat pada alternator diam sedangkan untuk generator berputar.
• Kumparan medan pada alternator dan generator terbalik dengan kumparan pembangkit. Untuk alternator berputar dan generator diam.
• Produksi arus pada alternator tidak memerlukan regulasi sedangkan untuk generator perlu untuk diregulasi.
• Keuntungan yang didapat dari alternator adalah pada putaran rendah sudah dalam tegangan yang cukup sedangkan pada generator pada putaran rendah tegangan yang dimiliki kecil.
• Kerugian atau yang lebih baik disebut dalam kekurangan adalah generator memerlukan tempat yang lebih luas dibandingkan alternator. (Source)

Countries are eligible to achieve waiver or discount from (Paid Journal Editor)

All authors who are eligible for a Research4Life Article Publishing Charge (APC) waiver or 50% discount will automatically see information after acceptance of their article in the rights and access forms informing them about the APC waiver or discount depending on their eligibility criteria.

How to check if you are eligible for a Research4Life APC waiver or discount?

The waiver or discount will depend on the location of the authors institution:

- 100% APC waiver: The corresponding author and co-authors must be all from a Group A country institution
- 50% APC discount: The corresponding author and co-authors must be all from a Group B country institution
- 50% APC discount: A mix of authors from Group A and B countries
- No Research4Life waiver or discount: A mix of authors from non-Research4Life countries and Group A or/and B countries
