Generator (English: Electric generator) is a device which converts mechanical energy into electrical energy. The device will force the electricity to flow through the external circuit. The source of mechanical energy could be a piston or turbine engines. Or force waterfall through the turbine wheel or water. Or internal combustion engines or turbines [1] or hand crank, or compressed air or other mechanical energy source A generator to power almost all electric power grid in the year to 1827 Anyos Hungarian Jedlik started with electromagnetic equipment rotate. Which is called the electromagnetic rotor spinning, now called the dynamo of Jedlik in the prototype of the starter electric pole single (completed during the year to year 1852 1854) both parts and a stationary ชิ้นส่วนหมุน electromagnets. He thought the recipe is the concept of dynamo for at least 6 years Siemens and Wheatstone but did not patent because he thought that he wouldn"t be the first to know about this. In essence, the concept is that instead of using permanent magnets. Two electromagnetic induction causes place opposite magnetic field around the rotor It also discovered the principle of self stimulation 2 as well [].Faraday generator first machine plate magnetic horseshoe (A) creates a magnetic field through the plate (D) when the plate is rotated. Will the induced electricity is the radius of the circle from the center to the edge of the plate. Current will flow out through the spring sliding touch m through the external circuit and back into the center of the plate through the central axis.In 1831-1832, Michael Faraday, discover the working principle of a generator from the electromagnetic principle, which later called the rule of Faraday. There is a strong induction conductivity is generated in the conductor. Electric enclosed magnetic field is changed. He also created from the electromagnetic generator is called Faraday plate machine first. Which is a type of generator by using a homopolar sheet copper plate rotate between the polarity of the magnetic horseshoe. It produces a DC voltage is small.
