generator is working everyday
Before the connection between magnetism and electricity was discovered, electrostatic generators were invented that used electrostatic principles. These generated very high voltages and low currents. They operated by using moving electrically charged belts, plates and disks to carry charge to a high potential electrode. The charge was generated using either of two mechanisms:
· Electrostatic induction
· The triboelectric effect, where the contact between two insulators leaves them charged.
Because of their inefficiency and the difficulty of insulating machines producing very high voltages, electrostatic generators had low power ratings and were never used for generation of commercially-significant quantities of electric power.
With the rapid development of technology, all kinds of modern generators are invented and used in every area of our daily life, and there is a lot of enterprise involved in producing generator, these generators offer families and companies comfortable and convenient life, which is especially important in today’s life. For example, now Generac is committed to produce generator to residential, commercial, industrial, portable and RV.
Here are the structure of generator, a conventional motor is rotated by outside working, that is, transform electric power into mechanic power after power on; whereas generator takes advantage of the change of magnetic flux to produce sensitive electromotive, that is, transform mechanic power into electric power, while general conventional generator/motor is of rotation type, that is, all mechanic power output by rotation work, or generate electric by the work of rotation; the generator/motor in current market normally apply Faraday’s law or Lenz’s law as generating or driven principle
