Generator vs alternator

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. An alternator always induces an alternating current. ... Generators have a lower output when compared with an alternator.

2. Components of an Electric Generator The main components of an electric generator are given below The Frame – the structure An Engine – source of mechanical energy The Alternator – produces an electrical output from the mechanical input A Fuel System – to keep the generator operational A Voltage Regulator – to regulate the voltage output A Cooling System – to regulate heat levels that build up in the system A Lubrication System – for durable and smooth operations over a span An Exhaust System – to dispose of the waste exhaust gases produced in the process A Charger – to keep the battery of the generator charged Main Control – the control panel controlling generator interface

3. GENRATOR What is generator ? A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energy . Output Current A generator can generate either alternating or direct current . Energy Efficiency Generators are considered less efficient. ALTERNATOR What is Alternator ? An alternator is a device that converts mechanical energy into AC electrical energy . Output Current An alternator always induces an alternating current . Energy Efficiency Alternators are very efficient.

4. GENRATOR Output Generators have a lower output when compared with an alternator . Energy Conservation Generators use all the energy that is produced and so, they conserve less energy . Magnetic Field In case of a generator, the magnetic field is stationary or fixed where the armature winding spins . ALTERNATOR Output Alternators have higher output than generators. Energy Conservation Alternators use only the required amount of energy and thus, it conserves more energy. Magnetic Field The magnetic field is rotating inside the stator of an alternator.

6. GENRATOR ALTERNATOR Armature Movement The armature of a generator is rotating. Input Supply The generator takes input supply from the rotor . RPM (Rotation Per Minute) Range Generators have a low range of RPM. Armature Movement The armature of an alternator is stationary . Input Supply The alternator takes input supply from the stator. RPM (Rotation Per Minute) Range Alternators have a wide range of RPM.

7. GENRATOR ALTERNATOR Size Generators are larger and require more space to fit in . Brush Efficiency The brushes of generators last lesser when compared to an alternator. Charging of a Dead Battery A generator can be used for charging a dead battery. Size Alternators are generally smaller in size Brush Efficiency The brushes of alternators last longer . Charging of a Dead Battery Alternators will never charge a dead battery.

8. GENRATOR ALTERNATOR Uses Generators are widely used to produce large-scale electricity. Uses Alternators are mainly used in the automobile industry as a charging system for the battery. GENRATOR
