    Faraday Discovery.

    Electromagnetic induction phenomenon.

    From 1821 to 1831, Faraday spent 10 years, from the idea to the experiment, the long years, the pain of failure, the hardships of life, Faraday tasted all kinds of bitterness, after countless repeated research experiments, finally discovered the phenomenon of electromagnetic induction.

    Found. Dynamo.

    Basic principle. Take advantage of this.

    Principle. Faraday.

    created. Electromagnetism.

    The first in history.

    Induction generators.

    But the Frenchman Pixie applied.

    Electromagnetic induction. The principle made the original generator.

    Pixi's generator is in close proximity to a U that can rotate

    shaped magnet (by handwheel and.

    Cogs. make it rotate) with two sticks.

    Iron core. Wrap it up.

    Conducting wire. Coil.

    Make it align with the n of the magnet respectively

    pole and spole, and lead the coil wire out. In this way, the handwheel is cranked so that the magnet rotates when it is due.

    Current. by such generators.

    Device. It can be known that whenever the magnet rotates half a turn, the coil corresponds to the magnet's.

    Magnetic pole. Change it once, so that the direction of the current changes once as well. In order to change this situation so that the direction of the current remains the same, Pixi came up with an ingenious solution: in the magnet.

    Rotary shaft. Two pieces are separated from each other.

    Cylinder. The shape of a metal piece, two threads drawn from the coil, warp.

    Springs. It is in contact with two metal sheets. In addition, two wires are used to contact the two metal sheets to draw out the current. This device is called.

    Commutators. It is still used in later generators.

    Why can commuters.

    Hold current. What about the same direction? This is because the current flows from the coil into the commutator, which rotates with the magnet.

    When the magnet turns half a turn, the direction of the current in the coil is reversed, and the commutator also turns around for half a turn and turns the direction, so the output current direction is always the same.

    Pixie invented this generator in.

    in the world. It is a first, but of course it has its drawbacks. The areas that need to be improved are: first, rotating the magnet is not as convenient and flexible as rotating the coil; The second is that the directional current can be obtained through the commutator, but the current.

    Strength. It's still ever-changing. In order to change this situation, people use the method of increasing the number of magnets and coils, and slightly staggering the changing currents together to make the output current.

    Strength. The change is controlled within a certain range.

    30 years after the invention of the generator from Pixey

    Over the years, although there have been improvements and some new inventions have appeared, the results have not been large, and the output image has never been developed.

    Battery. Such a large current, and can be used for practical generators.

    Electromagnetic induction is a generator. Generators are made according to the principle of electromagnetic induction. The power generation process of the alternator is that the closed coil rotates in the magnetic field, and the electromagnetic induction phenomenon is used to generate induced current, so its power generation principle is electromagnetic induction, and the electromagnetic induction is placed in the conductor in the changing magnetic flux, which will produce induced electromotive force.

    Principle of electromagnetic induction generatorThe generator uses external force to drive the generator to rotate, drive the conductor to cut a fixed magnetic field, the fixed magnetic field is called the stator, the rotating conductor is called the rotor, while generating voltage, the conductor is subjected to the resistance reaction force, that is, the work of the thrust is converted into electrical energy output, if the input of electric energy, the rotor will be rotated by the thrust, this reverse process is the motor.

    The basic element of the generator is the prime mover rotor stator to provide energy to drive the rotor to rotate, the rotor uses remanence or direct current to generate a magnetic field, when the rotor rotates, the stator will form a relative cutting magnetic field line movement, on the stator will produce an induced potential, if the stator and the external circuit are connected to form a closed loop, there will be a current output to the load.

    Generators work on the principle of electromagnetic induction.

    It converts mechanical energy into electrical energy through the relative motion of the rotor magnetic field and the stator windings. When the rotor is driven by an external force, the magnetic field of the rotor and the stator conductor move relatively, that is, the conductor cuts the magnetic field lines, so the induced electromotive force is generated in the conductor, and its direction can be determined according to the right-hand rule.

    Since the position of the rotor poles causes the conductor to cut the magnetic field lines in a perpendicular direction, the induced electromotive force in the stator windings is at its maximum. When the poles are turned 90 degrees. The magnetic poles are in a horizontal position, the conductor does not cut the magnetic field lines, and its induced electromotive force is zero.

    The rotor is rotated another 90 degrees, and the timing stator windings cut the magnetic field lines in a perpendicular direction, so that the induced electromotive force reaches the maximum value, but in the opposite direction.

    When the rotor is rotated another 90 degrees, the induced electromotive force becomes zero again. In this way, the rotor rotates for one revolution, and the induced electromotive force of the stator winding also changes positively and negatively. If the rotor rotates continuously at a constant speed, an alternating electromotive force is induced in the stator windings that changes periodically.

    The generator principle is a phenomenon of electromagnetic induction.

    A generator is a device that converts mechanical energy into electrical energy, and its working principle is based on the phenomenon of electromagnetic induction. According to Faraday's law of electromagnetic induction, when a conductor moves in a magnetic field, an induced electromotive force is generated at both ends of the conductor. Generators use this principle to convert mechanical energy into electrical energy by rotating a conductor (usually a coil) in a magnetic field, so that the free electrons inside the conductor are subjected to the unpredictable action of the magnetic field to generate an electric current.

    This principle is widely used in various types of noisy generators, including automobile generators, wind turbines, hydroelectric generators, etc.

    In addition to generators, electromagnetic induction phenomena are also widely used in transformers, induction heating, induction welding and other fields.

    In the cylinder of the gasoline engine, the mixture is violently combusted, and the volume expands rapidly, pushing the piston down to work. Whether it is a diesel generator or a gasoline generator, each cylinder works in a certain order, and the thrust acting on the piston becomes the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate.

    The brushless synchronous alternator is coaxially installed with the crankshaft of the power engine, and the rotor of the generator can be driven by the rotation of the power engine, and the generator will output induced electromotive force by using the principle of 'electromagnetic induction', and the current can be generated through the closed load circuit.

    Hello dear, the principle of electromagnetic induction of generators refers to the phenomenon of potential difference generated by the movement of a magnetic field. Specifically, it is the use of electromagnetic induction caused by the movement of conductors in a magnetic field to generate electrical energy. Generally speaking, it is the process of using the magnetic field through the action of the conductor to make the electrons inside the conductor move under the action of the magnetic field, so as to produce the potential difference between the two ends of the conductor, generate the current, and realize the process of energy conversion.

    In a generator, a permanent magnet or an external current is used to excite the magnetic field of the generator, which interacts with the conductor to convert mechanical energy into electrical energy. The specific process is as follows: the mechanical energy is input to the rotor through the rotating shaft, so that the conductor coil on the rotor moves under the action of the magnetic field, and the electrons in the conductor coil are moved by the action of the magnetic field force of the base, so as to generate electromotive force on the conductor, and then generate current, and finally output electric energy.

    The electric energy is output by the motor, which drives the relay, generator and withstand gear motor, motor and other electrical equipment to work. Hope mine is helpful to you, thank you and have a great day!

After the spiral coil is passed through direct current, it will form the N pole and the S pole at both ends of the coil. In fact, the generator rotor uses this principle to make an electromagnet with a magnetic core, and adjusts the magnetic field strength by adjusting the size of the excitation current, so as to achieve the purpose of adjusting the output voltage of the generator.
