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)
