Generator

Based on Fuel Type:

Diesel Generator – Runs on diesel fuel, commonly used for backup power.
Petrol (Gasoline) Generator – Runs on petrol, used for small-scale applications.
Natural Gas Generator – Uses natural gas as fuel, more eco-friendly.
Propane (LPG) Generator – Runs on liquid propane gas.

Based on Power Output:

Portable Generator – Small, movable units for temporary use
Standby Generator – Used as backup power for homes or businesses, automatically starts during power outages.
Industrial Generator – Large-scale generators for factories, hospitals, and power plants.

Based on Current Type:

AC (Alternating Current) Generator – Used in homes and industries for standard electricity supply.
DC (Direct Current) Generator – Used for battery charging, automotive applications, and welding.

Based on Phase Type:

Single-phase Generator – Supplies power for small appliances and residential use.
Three-phase Generator – Used in industries and large commercial buildings for heavy loads.

Based on Cooling Method:

Air-cooled Generator – Uses air circulation to cool the system, suitable for small generators.
Water-cooled Generator – Uses a water-based cooling system, used in high-power applications.

Based on Mode of Operation:

Self-excited Generator – Uses its own generated power to maintain the magnetic field.
Separately Excited Generator – Requires an external power source for excitation.
