History and basic principles of electric motor

It’s incredible how many devices around us today are powered by electric motors. With this video JAES wants to give an overview of the history and the basic principles of electric motors. You can visit our online catalogue to see all the electric motors manufacturers : https://www.jaescompany.com/ It’s incredible how many devices around us today are powerd by electric motors. Whether it’s a simple blender, a fan, a vacuum cleaner, or even a car or public transportation. The most common engines use internal combustion to create heat, this is not the case with electric motor. Electric motor is powered by a complete different principle. Don’t you believe me? Looking at this animation: you can see a wire connected to a battery. When the electricty flows through this wire, an electromagnetic field is created. This means that the electricity has temporarily turned the wire into a magnet. When the wire is disconnected from the battery, is not a magnet anymore. If we hook it up the opposite way, it’s north and south pole reverse. An electric motor makes this process over and over, using the magnetic force to create mechanical motion. Now let's take a step back to explain in detail the basic elements of this process: ELECTRIC CURRENT simply is a flow of electric charge, which means moving electrons in a wire. Their motion is caused by an electric potential difference between two points of a conductor. This difference allows the electrons to flow from the negative pole to the positive pole. A CONDUCTOR is an object or type of material that allows the flow of an electrical current in one or more directions, like metals and alloys. A MAGNET is an object that produces a magnetic field. Each magnet have a North and a South pole. Inside a magnet there will be alway a South and a North pole. Even dividing the magnet into two parts, the remaining parts will have a north and a south pole. A MAGNETIC FIELD is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets. Many materials can be magnetized. It seems that Archimedes tried to magnetized the Syracusan army weapons in order to easily disarm the enemies. Electric motors requires electricity for their functioning. The common Plugs and sockets represent Alternating current, an electric current which periodically reverses direction. Batteries represent Direct current, an electric current which flows only in one direction. It’s hard to enumerate the long list of inventors who tried to make pratical the conversion of electrical energy into mechanical energy. In any case we can draw a timeline of the most significant inventions for the development of today's electric motors In eighteen hundred, for the first time, italian Allessandro Volta produces a continuous electrical power from a stack of silver and zinc plates.
