- What is an alternator and its working?
The alternator works by turning mechanical energy into electrical energy. When your engine is on, it powers a drive belt that rests on a pulley attached to the alternator. The pulley turns the alternator's rotor shaft, which spins a set of magnets inside a coil.
What is called alternator?
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. Any AC electrical generator can be called as an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines

Sure. An AC 3-phase alternator is an electrical machine that converts mechanical energy into electrical energy in the form of alternating current (AC). It has three sets of windings, called phases, that are arranged 120 degrees apart. When the rotor, which is the rotating part of the alternator, is spun by a prime mover, such as a gasoline engine or a turbine, it creates a rotating magnetic field. This rotating magnetic field induces an AC current in each of the stator windings. The magnitude and frequency of the output current are determined by the speed of the rotor and the number of turns in each of the stator windings.
The main components of an AC 3-phase alternator are:
Rotor: The rotor is the rotating part of the alternator. It is made of a ferromagnetic material, such as iron or steel, and has a number of poles, which are projections that create the rotating magnetic field.
Stator: The stator is the stationary part of the alternator. It has three sets of windings, which are arranged 120 degrees apart.
Rotor field winding: This winding is used to create the rotating magnetic field. It is usually connected to an external DC source.
Stator winding: This winding is where the AC current is induced. It is usually connected to the load circuit.
Bearings: The bearings support the rotor and allow it to spin freely.
Cooling system: The cooling system removes heat from the alternator, which is generated by the friction of the rotor and the stator windings.
The working principle of an AC 3-phase alternator is based on the principle of electromagnetic induction. When a conductor is placed in a changing magnetic field, an electric current is induced in the conductor. The rotating magnetic field of the rotor induces an AC current in the stator windings. The magnitude and frequency of the output current are determined by the speed of the rotor and the number of turns in each of the stator windings.
AC 3-phase alternators are used in a variety of applications, including:
Power generation: AC 3-phase alternators are used to generate electricity for commercial and industrial use.
Machine drive: AC 3-phase alternators are used to drive machinery, such as motors and pumps.

Excellent video thanks
Thank you for sharing this video with us. I would like to learn more about electrical side of the Generator. I am an electrician.
Sir Generator circuit breaker local control pr zaror one video banawo
Samjha nahi mai ap ka sawal
Sir old Generator control penal me circuit breaker local control ka opposition hora hai
Hai brother
Thank you for the information.
Let me know which type of generator is recommended to use in distributions (stand by,prime or remote location)purpose.Permenent magnet excitation or field excited?why?appreciate to explain in value engineering perspective of a building service or MEP electrical engineer.
Let me check
Thx sir finally my dout is clear how the first voltage produc.😅
Glad it helped
Good day boss,,I have a question my genset is always blown or burn the varistor while put a load,what is the possible cause of it,,thanks
What is load type what equipment is connected and what is the percentage load your applying in first step
@@DieselGeneratortraining actually boss that was in power plant with 6 synchronized genset supplying power into the building,the was only around 30% of load ,I haved 1 genset always burning varistor that was 2 times happened in the same genset,,what can u advise,, thanks
Why do my Cummins generators, each equipped with a Deep Sea controller, experience abnormal behavior when integrated into the system? Whenever we introduce one particular generator, it induces overcurrent in the previously operating generators, and itself produces excessive current (around 900 amps per phase) even with a light load. Upon removing this generator from the system, the remaining generators return to normal operation. Whether it's just this generator alone on load or multiple units, the problem arises consistently whenever we close the breakers specific generator and introduce load. What could be causing this issue, and how can we address it to ensure smooth operation of the system?
