Bixy
In 1832, the Frenchman Bixy invented the manual DC generator. Its principle is to modify the magnetic flux in the coil by rotating the permanent magnet. It induces electromotive force and produces results. this electromotive force in the form of direct voltage;
In 1866, the German company Siemens invented the self-excited DC generator;
In 1869, the Belgian company Gram manufactured it . He became an annular armature and invented the annular armature generator. This type of generator uses hydraulic power to turn the generator rotor. After repeated improvements, it reached an output power of 3.2KW in 1847;
In 1882, Gordon of the United States produced a generator with an output power. of 447KW A giant two-phase generator with a height of 3 meters and a weight of 22 tonnes.
Detailed information:
Generators are widely used in productionindustrial and agricultural ion, national defense, science and technology and daily life. There are many forms of generators, but their operating principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: using suitable magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction among themselves to generate electromagnetic energy and achieve the conversion goal of energy.
Generator detection steps:
Step 1: Check for disconnections, connection errors or short circuits at the external conductor connection parts from the generator and use a voltmeter to measure. the voltage at point B+ No battery voltage.
Step 2: Turn the key door to the “open” position, mbut do not start the engine. At this time, use a voltmeter to measure whether there is voltage at point D+ and observe whether charging. the indicator light is bright.
Step 3: Start the engine and use a voltmeter to measure the voltage at point B+ of the engine. It should reach the following value.
Step 4: Turn on some loads, such as. as car headlights
Step 5: Turn on major electrical appliances such as air conditioners and car headlights
