Question 2: Who was the inventor of the first generator in the world? The inventor of the first generator in the world was a Frenchman named Pixar.
Faraday, a British scientist, discovered the principle of electromagnetic induction in 183 1 year. This principle, which plays an important role in the development of human society, says: "When the magnetic field lines change, current will be induced in the wires around them."
Faraday painstakingly, through research and repeated experiments, finally discovered this influential scientific principle, and he was convinced that a generator that could really generate electricity could be made by using this principle.
In the second year after Faraday discovered the principle of electromagnetic induction, inspired by Faraday's discovery, the Frenchman Pisci made the first generator by applying the principle of electromagnetic induction. Pixie's generator is close to the rotatable U-shaped magnet (driven by handwheel and gear), and two iron cores are wound on the wire coil, which are aligned with the N pole and S pole of the magnet respectively, and the wires of the coil are led out. In this way, when the handwheel is shaken to rotate the magnet, the magnetic field lines change, and as a result, current is generated in the coil conductor.
Question 3: Who invented the generator? 183 1 year, Faraday invented the earliest generator in the world. 1832, the Frenchman pi Iscu invented the hand-driven generator. 183 1, Faraday passes a wire in a closed circuit through an electromagnetic field, and a current flows through the wire when the wire rotates. Faraday therefore realized that there was a close relationship between electricity and magnetic field. He built the prototype of the first generator, which included a copper disk rotating in the magnetic field, thus generating electricity. Before that, all the electricity was generated by electrostatic machines and batteries, and they could not generate much power. However, Faraday's generator finally changed everything. The generator includes an electromagnet that can rotate rapidly between two or more magnetic fields. When two magnetic fields cross each other, electricity is generated and led out of the generator by wires. Electronic engineers get alternating current (AC) or direct current (DC) according to the winding mode of the generator and the arrangement of magnets. Most generators generate alternating current, which is easier to transmit over long distances through transmission lines than direct current. Anyone who has studied physics will remember that Faraday, a British scientist, discovered the principle of electromagnetic induction in 183 1 year. This principle, which plays an important role in the development of human society, says: "When the magnetic field lines change, current will be induced in the wires around them." Faraday painstakingly, through research and repeated experiments, finally discovered this influential scientific principle, and he was convinced that a generator that could really generate electricity could be made by using this principle. In the second year after Faraday discovered the principle of electromagnetic induction, inspired by Faraday's discovery, the Frenchman Pisci made the first generator by applying the principle of electromagnetic induction. Pixie's generator is close to the rotatable U-shaped magnet (driven by handwheel and gear), and two iron cores are wound on the wire coil, which are aligned with the N pole and S pole of the magnet respectively, and the wires of the coil are led out. In this way, when the handwheel is shaken to rotate the magnet, the magnetic field lines change, and as a result, current is generated in the coil conductor. In the generator device, every time the magnet rotates for half a turn, the magnetic pole of the magnet corresponding to the coil changes once, so the direction of current also changes once. In order to change this situation and keep the current direction unchanged, Pixie came up with an ingenious method: two metal pieces separated from each other are added to the rotating shaft of the magnet, and the two ends leading out of the coil are in contact with the two metal pieces respectively through spring pieces. In addition, two wires are in contact with two metal sheets to draw current. This device, called commutator, was still used in later generators. The generator invented by Pixie is the first in the world, but it also has some shortcomings. Need improvement. First of all, rotating magnets is not as convenient and flexible as rotating coils. Secondly, directional current can be obtained through rectifier, but the current intensity is still changing. In order to change this situation, people adopt the method of increasing the number of some magnets and coils, and leading out the changed current slightly staggered, so as to control the intensity change of the output current within a certain range. In the more than 30 years since Pixie invented the generator, although some improvements have been made and some new inventions have appeared, the results are not great, and a generator that can output as much current as a battery and can be used in practice has never been developed. 1867, the German inventor Werner von Siemens made a major improvement on the generator. He believes that using electromagnets instead of magnets (that is, permanent magnets) can enhance the magnetic force and generate powerful current. The principle that Siemens uses electromagnets instead of permanent magnets to generate electricity is that the iron core of electromagnets still has weak magnetism in the absence of current. When the coil rotates, the weak remanence is used to generate current, which is then fed back to the electromagnet to enhance its magnetic force, so that the electromagnet can also generate strong magnetism. Then, Siemens began to study electromagnetic generators. This new type of generator was soon made, which can generate a powerful current far exceeding that of Pique generator. At the same time, this kind of generator is much more convenient than connecting many batteries to power on, so it is widely used as a practical generator. Shortly after Siemens' new generator came out, Italian physicist Pachinuti invented the ring generator armature in 1865. This armature replaces the coil wound on the iron core bar with the coil wound on the iron ring, which improves the efficiency of the generator. In fact, Pasnuti put forward the idea of generator armature as early as 1860, but it failed to attract people's attention. 1865, he published this unique opinion in a magazine ... >>
Question 4: 183 1 who invented the first generator? Shortly after Faraday discovered electromagnetic induction, he invented the world's first generator-Faraday disk generator by electromagnetic induction. The structure of this power generation mechanism is different from that of modern generators. It is not a coil that rotates in the magnetic field, but a disk made of copper. A crank is fixed on the center of the circle (Figure 9-3). A brass brush is attached to the edge and center of the disc respectively, and the brush is connected with the ammeter through wires. A copper disk is placed in the magnetic field of a horseshoe magnet. When Faraday turned the handle to turn the copper plate, the pointer of the ammeter tilted to one side, indicating that a continuous current was generated in the circuit.
Question 5: Who invented the generator? Where is he from? Michael. Faraday, British physicist
Question 6: Who invented the first generator? Siemens electric energy is one of the most important energy sources in modern society. Generator is a kind of mechanical equipment that converts other forms of energy into electrical energy. It was first produced during the second industrial revolution and was manufactured by German engineer Siemens in 1866. It is driven by water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, airflow, fuel combustion or atomic nuclear fission into mechanical energy, which is transmitted to the generator, and then converted into electrical energy by the generator. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life.
Question 7: Who invented the motor? 1834 German Jacob invented the DC engine.
1888 Tesla, a Yugoslav-American, invented the AC motor.
182 1 year, the British scientist Faraday first proved that electricity can be converted into rotary motion. The first person to make an electric motor is said to be jacoby. 1834, it became a simple device: a six-arm wheel was installed between two U-shaped electromagnets, and two bar magnets were installed on each arm. After electrifying, the mutual attraction and repulsion between the bar magnet and the U-shaped magnet drives the axle to rotate. Later, jacoby made a big device. Installed on a small boat, powered by a 320-Daniel battery, the boat sailed on the Elbe River for the first time in 1838, with a speed of only 2.2 kilometers per hour. At the same time, Davenport of the United States has also successfully built a motor to drive the printing machine, printing electromagnetic and mechanical information, a sentence of the American electricity semester. However, these two kinds of motors are of little commercial value, and it is too expensive and impractical to use batteries as power supply.
It was not until the first practical DC engine came out that the motor was widely used. 1870, Belgian engineer Gram invented DC generator, which is similar to motor in design. Later, Gram proved that the rotor of DC engine will rotate like a motor when current is input. As a result, this kind of dynamoelectric machine was mass-produced. Efficiency is also constantly improving. At the same time, Siemens in Germany made better generators and began to study vehicles driven by electric motors, so Siemens made the world trams. 1879, Siemens' smokeless tram won applause from the audience at the Berlin industrial exhibition. Siemens electric locomotive was only 3 horsepower at that time. Later, the electric locomotive tested by American inventor Edison reached 12- 15 horsepower. But the engines at that time were all DC cars, which were limited to driving trams.
1888, Tesla, an American inventor born in Yugoslavia, invented the AC motor. It is made according to the principle of electromagnetic induction, also known as induction motor. This kind of motor is simple in structure, uses alternating current, does not need rectification and has no spark, so it is widely used in industrial household appliances. Alternating current motors are usually driven by three-phase alternating current.
1902 Swedish engineer Danielson first put forward the idea of synchronous motor.
The working principle of synchronous motor is the same as that of induction motor. The stator produces a rotating magnetic field, so the rotor winding is powered by DC, and the speed is fixed and is not affected by the load. Therefore, synchronous motors are especially suitable for clocks, record players and tape recorders.
The DC motor is DC-excited, and its working characteristics are different due to the connection mode of the excitation winding. Series motor has large starting torque and is suitable for traction and hoisting. The speed of parallel motor changes little with the load, which can be adjusted and can be used for constant speed or speed regulation. The compound motor has the characteristics of the above two kinds of excitation engines.
AC commutator motor, that is, AC motor with commutator rotor. Because it can be used for both AC and DC, it is called AC -DC dual-purpose motor or universal motor, which is mostly used in household appliances.
