Electric Machines Drives Projects for MTech
In electrical engineering, electric machine is a common term for electric motors along with electric generators and further electromagnetic machines. They are electro mechanical energy converters: an electric motor transforms electricity to mechanical power whereas an electric generator transforms mechanical power to electricity. The affecting parts in a machine can be rotating (rotating machines) or linear (linear machines). Apart from motors and generators, a third category repeatedly included is transformers, which while they do not have any moving parts are also energy converters, altering the voltage level of an AC.
An electric generator is a tool that transforms mechanical energy to electrical energy. A generator compels electrons to flow via an external electrical circuit. It is rather similar to a water pump, which creates a water flow but does not make the water inside. The source of mechanical energy, the prime mover, may be a reciprocating or turbine steam engine, water falling via a turbine or waterwheel, an inner combustion engine, a wind turbine, a hand crank, compressed air or any other supply of mechanical energy.
