The word motor has been associated with various things in our daily lives from the beginning. We have heard of this word as a close counterpart to many machines such as motorcycles, motorboats, and motor cars. Going back to the jargon, many years ago, people used to refer to a car as a “gaadi engine”. But have we ever bothered to take a look at what “electric motors” look like, or what exactly is a motor? What is its composition or how does it work? Let’s make a brief summary of this aspect of electric motors that is so much talked about, but is superficially known.
An electric motor is a machine that converts electrical energy into mechanical energy. But how does it work? Here’s the answer: the basic idea or basic principle of motors is that they cause the interaction of magnetic fields and current-carrying conductors, and the output is force. This force serves the operation of the engines. It is all about magnets and magnetism, so if you are knowledgeable about magnets and their laws, understanding the concept of those motors is not a difficult task for you. Few electric motors also use electrostatic forces.
The reverse process, that is, converting mechanical energy into electrical energy, is carried out by generators such as an alternator or a dynamo. Various types of electric motors can be used in the form of generators. Medium-sized motors of highly standardized dimensions and characteristics serve as a good source of mechanical power for industrial uses. The largest electric motors are used to power ships, pipeline compressors, and water pumps with ratings of millions of watts. Motors can be classified by the source of electrical energy, by their internal construction, by their application or by the type of movement they give.
The first conversion of electrical energy into mechanical energy by electromagnetic means was demonstrated by the British scientist Michael Faraday in 1821. This was the principle of electric motors.
Almost all machines have a motor. Mechanical movement is the result of AC (alternating current) or DC (direct current).

Understanding the workings of electric motors can help you a lot in understanding the workings of magnets, electromagnets, and the fundamentals of electricity. You will no longer be left with queries and concerns on your mind, when you find yourself stuck in a situation where you have to deal with electrical things.
The idea of electric motors has not been limited to household appliances; It has been used extensively elsewhere due to its efficiency and results. For, for example, electric cars, pumps, boats, bicycles. Its use demonstrates good operation and a pollution-free environment.
